Added tests for multiple topics, created date, updated date, and stars.

Added additional tests for multiple topics, created date, update date, and star count. The tests do fail occasionally, but this appears to be an issue in main as well. This will require a different commit to resolve.

Added additional tests for multiple topics, updated date, add date, and star count. Modified a few comparisons to None to use "is None" rather than "== None", as advised by pylint.

Thanks @arcanearronax, before your latest commit I think that the tests failed because we used repo[‘updated_at’] Instead of repo[‘pushed_at’]

I'll need to take a second look at that since I thought I verified the data point. Part of the issue I was running into was the unauthorized request limit since I was running into failures after repeated runs.

Once I'm back at my computer I'll open a bug to handle unauthorized requests, since those seem to result in unhandled key errors.
