`select last_insert_rowid()` doesn't account for ROLLBACK on transaction

We probably don't want to use the SQLIte function `last_insert_rowid()` to get the last_pk. Per the docs on [last_insert_rowid](https://www.sqlite.org/c3ref/last_insert_rowid.html), this is expected behavior:

> For the purposes of this routine, an [INSERT](https://www.sqlite.org/lang_insert.html) is considered to be successful even if it is subsequently rolled back.

Get last rowid

```sql
SELECT last_insert_rowid();
```

`0`

Now do the transaction and check the row id:

```sql
BEGIN TRANSACTION;
INSERT INTO users (username) VALUES ('puppy');
SELECT last_insert_rowid();
```

`1`

Roll the transaction back and check the table and rowid:

```sql
ROLLBACK;
SELECT last_insert_rowid();
```

`1`
