revert: don't assume ignored files will be returned in the unknown list

That's just an artifact of the current implementation, and I'll change
that soon.

Bonus points:
- we don't care about the unknown list at all
- we don't print an extra message if we try to revert a removed file
  that is not present in the target revision
