[welcome] Fix up and expand tests

- improve logging
- fix failing tests -- the observed and expected behavior is
  to fill in a fallback check-URL, not change to an empty list,
- **except** if there's no requirements key in the config
  at all; this is a bit weird, but let's make the tests
  document existing behavior so we can notice if it changes.
