    libtracker-miner: Do not recurse up the hierarchy for out-of-tree index requests
    
    If we receive a tracker_miner_fs_check_file() request for a file out of
    indexing trees, it'd usually end up recursing until it ran out of parents
    (that is, up to file:///). This is quite pointless, if only one file was
    requested to be indexed.
