    libtracker-miner: don't crash when first indexing files out of /home
    
    If tracker_miner_manager_index_file() is called with a path outside of
    the home directory, we'll end up recursing up to the file system root,
    to create the parent directory objects.
    
    When the tree we're passed is the filesystem root, and the file is
    exactly equal to it, we should return the tree root immediately, or
    we'll crash later in the while loop.
