Subject: [PATCH] Set journal_mode to truncate for SQLite in tests

no issue

- we would regularly see IO errors coming from SQLite, which caused
  random regression tests to fail
- the default journal_mode is `delete`, but this is slow and can cause
  issues when multiple tests try to remove the journal file
- `truncate` is faster and shouldn't cause these issues
