tag: Fix restoring invalid tags from history (#963) 

If:

 1) An app is open in a tag
 2) A new tag is created
 3) The app is closed in the first tag
 4) The first tag is deleted
 5) The new tag is deleted

Then this history would try to restore an inactive tag without
a screen. Bad things will then happen.
