    tracker-miner-fs: Don't index duplicate MMC and config paths
    
    Previously, if a removable device was mounted on $HOME/foo and
    $HOME/foo was in tracker-miner-fs.cfg, it would be iterated twice. Now
    we check for this and drop the .cfg version in favour of the removable
    device mount point.
