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

[Carlos Garnacho <carlosg src gnome org>]

commit 27e3af563d4f10388f77284e773e3db838dfb70f
Author: Carlos Garnacho <carlosg gnome org>
Date:   Wed May 5 18:12:11 2010 +0200

    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.
