destroyed: keep the filecache in sync with __dict__ (issue3335) (issue3693) (issue3743)

We need to make sure that if X is in the filecache then it's also in the
filecache owner's __dict__, otherwise it will go out of sync:

repo.X                  # first access to X, records stat info in
                        # filecache and updates __dict__
repo._filecache.clear() # removes X from _filecache but it's still in __dict__
repo.invalidate()       # iterates over _filecache and removes entries
                        # from __dict__, but X isn't in _filecache, so
                        # it's kept in __dict__
repo.X                  # X is fetched from __dict__, bypassing the filecache
