test: Add tests for naming threads with changing subjects.

We recently added a feature to name threads based on the messages that
actually matched the search, (as opposed to simply the oldest or
newest message in the thread whether it matched or not). So add tests
for that, and (surprise, surprise!) the feature does not entirely
work.
