Fix spurious 'Missing event data' error for triggerEnd objectives with no coordinates

QuestieQuestPrivates.lua: event handler now returns nil silently when
Coordinates is nil, instead of logging a visible error. Nil coordinates
are valid for server-tracked objectives (complete N quests in zone) that
have no map pin.

Nil coordinates are valid for server-tracked objectives with no pin — the handler now returns silently instead of logging a visible error.
