Subject: [PATCH] fix: Race condition with tests and sqlite init

Should fix the error:

```
panic: SQL logic error: table `entities` already exists (1) [recovered]
	panic: SQL logic error: table `entities` already exists (1)
```

By using in-memory sqlite databases for tests instead of sharing one on
the filesystem.
