Ref T10978. Currently, too many "This audit now <something something>" transactions are posting, because this strict === check is failing to detect that the audit is already in the same state.

This is because audit states are currently integers, and saving an integer to the database and then reading it back turns it into a string. This is a whole separate can of worms. For now, just weaken the comparison. I'd eventually like to use string constants here instead of integer constants.

Commented on a "no audit required" commit, didn't see a double "this doesn't need audit" transaction anymore.

Also made a legit state change and did see a state transaction.
