Misc small `SqlImplementation` issues

I was going to make an issue about having a problem with `SqlImplementation.entities()` not getting any entities and producing errors, but I think I'm having more general problems with `SqlImplementation`.

**My version:** `oaklib==0.1.23`
_edit:_ I realize now that this is outdated. I fixed that on my end. I will need to re-run and see if still empty.

# Sub-issue list
Checked means fixed.
- [ ] 1. Orphan `.template.db.tmp`
- [ ] 2. Unsquelched `stdout`
- [ ] 3. Unhandled error: missing local file
- [ ] 4. Interactive `sqlite` session when running Python script from makefile
- [ ] 5. `.entities()` returns nothing

# Sub-issues
## 1. Orphan `.template.db.tmp`
I think that it hung at some point; possibly related to issue (4) below. I think that when I terminated, OAK did not exit gracefully and delete this temp file from the directory where I called.

This still applies to `0.2.0`, when using OAK or `semsql` separately.

## 2. Unsquelched `stdout`
Last tried version: `0.1.23`
I don't know if this is useful to some users. I'd prefer not seeing it by default.

**What I ran**
From Python:
```py
ontology = SqlImplementation(OntologyResource(slug='mondo-ingest/src/ontology/components/omim.owl', local=True))
```

**Output**
```
cat /Users/joeflack4/virtualenvs/mondo-ingest/lib/python3.9/site-packages/semsql/builder//sql_schema/semsql.sql | sqlite3 .template.db.tmp && \
echo .exit | sqlite3 -echo .template.db.tmp -cmd ".mode csv" -cmd ".import /Users/joeflack4/virtualenvs/mondo-ingest/lib/python3.9/site-packages/semsql/builder//prefixes/prefixes.csv prefix" && \
mv .template.db.tmp .template.db
.exit
robot remove -i components/omim.owl --axioms "equivalent disjoint annotation" -o components/omim-min.owl
relation-graph --disable-owl-nothing true \
--ontology-file components/omim-min.owl\
--output-file components/omim-relation-graph.tsv.ttl.tmp \
--equivalence-as-subclass true \
--output-subclasses true \
--reflexive-subclasses true && \
```

**Possible solutions**
Add a `bool` argument `verbose` to the necessary super / interface classes, defaulting to `False`. Can then connect this to the CLI with a `--verbose` option.

## 3. Unhandled error: missing local file
I ran Python from my IDE:
```py
ontology = SqlImplementation(OntologyResource(slug='components/omim.owl', local=True))
```

But I think it had the wrong working directory at first, and I got this error:
> `make: *** No rule to make target `components/omim.db'. Stop.`

Suggestion:
Handle this exception and instead show something like:
> FileNotFoundError: 'components/omim.owl'

## 4. Interactive `sqlite` session when running Python script from makefile
My Python script got ran from a `makefile`. I believe that this is the line which triggered the following terminal output:
```py
ontology = SqlImplementation(OntologyResource(slug='components/omim.owl', local=True))
```

Terminal output:
```
/usr/local/lib/python3.10/dist-packages/rdflib_jsonld/__init__.py:9: DeprecationWarning: The rdflib-jsonld package has been integrated into rdflib as of rdflib==6.0.0. Please remove rdflib-jsonld from your project's dependencies.

sqlite3 -echo .template.db.tmp -cmd ".mode csv" -cmd ".import /usr/local/lib/python3.10/dist-packages/semsql/builder//prefixes/prefixes.csv prefix" -cmd ".exit" && \
mv .template.db.tmp .template.db
SQLite version 3.37.2 2022-01-06 13:25:41

sqlite>
```

This may be related to my issue (1) above. I think when I quit this, it may have left remnants of some temp DB file, but I'm not sure.

Also at some point, my terminal froze, and I tried CTRL+D plus like 7 other ways to try to kill the process, but I couldn't terminate and ultimately had to close the window. It may have been related to this issue; not sure.

## 5. `.entities()` returns nothing
This was the case for `0.1.23`. I haven't tried again using `0.2.0`, though I did see that my `0.2.0` DB that was created manually by `semsql` was not empty.

Start at SqlImplementation and its entities() entry point, then inspect the makefile commands and semsql/sqlite setup described in the report. Reproduce the five listed behaviors against the current version, since several observations were made on outdated releases. Done means each confirmed issue has a clear error or output behavior, with temporary files and interactive sessions handled appropriately.
