    tracker-miner-files: Only re-check tracker-extract if gone
    
    If we set up the DBus name watch and directly get a "name lost"
    callback (eg. if it failed to be autostarted), do not try to restart
    it again and again.
    
    This is only useful to kick tracker-extract back to working after
    eg. some crash, so just check that it was previously running.
