[gnome-photos] properties-dialog: Don't show the modification status for collections

    properties-dialog: Don't show the modification status for collections
    
    Collections don't have any pixels, actual images do, so it doesn't make
    sense to show the modification status for them. Trying to do so would
    lead to:
      CRITICAL **: photos_base_item_pipeline_is_edited_async: assertion
        '!priv->collection' failed
