So with this change we now run the tests for all "official" branches,
and on pull requests. Which raises the question: are there any events
that happen regularly that are excluded by this? Because if not I think
it might be sensible to just enable this unconditionally, also because
that would make jobs on GitLab CI run expensive tests, as well.
