fix up assertEqual(None...) check to catch more cases

To finally close out bug #1280522 it turned out that our hacking check
to eliminate assertEqual(None, ...) was pretty sub optimal. The
perfect fix would actually use the tokenizer, however this is a better
regex which catches a few more missing bits in our codebase. It's
probably close enough for most of what we need.

Fix the relevant tests that would fail the updating hacking check.
