    Fixes GB#621183: When mounting volume 2nd time, inotify watches don't work any more
    
    * src/libtracker-miner/tracker-miner-fs.c: Make sure all monitors are removed
    when a directory is no longer watched.
    
    * src/miners/fs/tracker-miner-files.c: Make sure directory is no longer
    watched when unmounting (in case we didn't get a pre-unmount signal)
