Can't run `dolt log` while a `dolt push` is running in another shell. No active sql-server.

This was reproduced on media_wiki database which has long running pushes. No sql-server was running.

In one shell:

```sh
$ dolt push
- Uploading...
```

In another shell:

```sh
$ dolt log
dial tcp [::1]:3306: connect: connection refused
$ dolt log
dial tcp [::1]:3306: connect: connection refused
```
