Always run required checks (#301)

We have quite sophisticated rules when to run which Molecule checks.
Unfortunately it's quite easy to have a PR or push where the full stack
checks won't run. But since we require these checks, you can end up in a
situation where you don't have check results but can't merge without
those results.

So I simplified the rules when to run these checks.

fixes #300
