make mq play nicely with the branch cache

- if no patches are applied, don't do anything different

- if the cache includes valid data from one of the patch revisions,
  use the cache, but don't save anything new

- if the cache has data from before the patch revisions only,
  save what the list of branches would be without the patch revisions
