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.

+- **[Quest]** Fixed "Missing event data for Objective" error appearing in chat for all `triggerEnd` quests with no map coordinates (e.g., "complete N quests in zone" types). Nil coordinates are valid for server-tracked objectives with no pin — the handler now returns silently instead of logging a visible error.
