[tracker/tracker-0.8] TrackerConfig: Preserve unfiltered list of recursive/single directories.



commit 19feecac29f43dc6329f45ce7d0fa4632157ed23
Author: Carlos Garnacho <carlosg gnome org>

    TrackerConfig: Preserve unfiltered list of recursive/single directories.
    
    The final list is post-processed, in order to have items in single dirs
    removed from the recursive list, two new functions allow getting the
    unfiltered list.
