[tracker/miner-fs-refactor: 3/120] libtracker-miner: Make TrackerMonitor use TrackerIndexingTree



commit 6a925cfb22d09d7c01e365a117d4f92cd94da10f

    libtracker-miner: Make TrackerMonitor use TrackerIndexingTree
    
    This is at the moment only used for event discarding, and for emitting
    the correct signal out of a MOVE event.
