[Debug] Adding wrappers around Mephisto's sqlite3 DB access

[JackUrb]

Overview

Wraps the creation of sqlite3 Connection objects such that, if any thread tries to access them from a different thread, we'll see this behavior occur. This covers all of the sqlite3 connections inside of Mephisto, so @mojtaba-komeili if you still encounter the bug but aren't receiving additional logging, we'll need to look into your task-specific code.

At the moment this is only a debug branch, and we may choose to remove later.
NOTE - it's possible that Mephisto is silently swallowing an error somewhere, but the debug logging here should point that out as well.

Testing

Automatic tests - currently failing. Will debug

Thanks for implementing it. I will start my next task run on this branch. Hopefully this solves it, this time.
