    core: Remove trailing '/' from GrlMedia IDs
    
    grl-launch-0.3 -S browse -k title grlbox://grl-tracker-source/videos/
    should have the same output as:
    grl-launch-0.3 -S browse -k title grlbox://grl-tracker-source/videos
    
    The first would get its ID parsed to "videos/" whereas the second would
    be parsed to "videos". Chomp the trailing '/'.
