Revert "libtracker-miner: Postpone TrackerIndexingTree::directory-removed emission"

This reverts commit 5b4ab760c4782d1b7a098605b69d547c9466d20e.

There's code relying on poking the removed directory flags one last time
during ::directory-remove, so we must prevent from recursion in some other
ways. Spotted during make distcheck.
