TrackNextActivityForZoneStory() acts like "show on map"

[Masteroshi430]

TrackNextActivityForZoneStory(ZoneID, nil, false) acts like "show on map" if the zone story activity is already in the quest tracker/journal.

Also GetZoneStoryActivityNameByActivityId(zoneId, zoneCompletionType, activityId) and GetZoneStoryShortDescriptionByActivityId(zoneId, zoneCompletionType, activityId) are equal to an empty string if the zone story activity is already in the quest tracker/journal.

Are these bugs or is there a way to avoid calling TrackNextActivityForZoneStory(ZoneID, nil, false) when the zone story activity is already in the quest tracker/journal?
