test: Print section names, and rename all test sections

Now that we can usefully pass section names via the NOTMUCH_SKIP_TESTS
environment variable, it's useful to actually print those names out
for the user. Then, since we're now printing these names, let's use
nicer names, (not excessively long but also not using abbreviations
like "msg").
