[glabels] Fix selection problem.

[Jim Evins <jimevins src gnome org>]

commit 55b7dda6b69c4f1a25734152fd6b69b72ee3f385
Author: Jim Evins <evins snaught com>

    Fix selection problem.
    
    Clear existing paths before creating new test paths.  This would occasionally
    cause the wrong object to be selected because the in_fill or in_stroke
    tests would be satisfied using left-over paths from previous tests.
