Fix bug #3515. identification of resources with discussion now occurs in lonfeedback after 'Mark all posts as read call'. To simplify further we might want to eliminate the extra code in lonnavmaps, called when sort is by "Has Discussion" and always do the resource->has_discussion call in lonfeedback.
