Expanded database testing

- Tested Submission.count descriptor
- Tested Submission.clear_other_votes
- Expanded Submission.advance testing to include exceptions, Submission
.active, Submission.completed and Submission.voting
- Changed db model __repr__ implementations to use f-strings
- Fixed Submission.update force kwarg not implemented.
- Small formatting changes, new TODO, noinspection on protected access
- Votes setter now removes duplicate keys (maintains order)
- Removed 'aiosqlite' from Pipfile general package requirements
