GetQuestObjectives returns nil for quests with no trackable objectives
on WotLK private servers. The original code set hasInvalidObjective=true
but left isQuestLogGood=true, causing goodQuestsCount to stay 0 while
numQuests was 19 -> 'Good quest: 0/19' error on every login/reload.
Treat a non-table return as an empty valid objective list. Demote the
Questie:Error to Questie:Debug so it doesn't spam chat.
Register BAG_UPDATE_DELAYED to catch autoloot objective updates.
Autoloot bots that bypass the loot frame skip QUEST_WATCH_UPDATE,
leaving the tracker stuck at a stale count. Setting doFullQuestLogScan=true
on BAG_UPDATE_DELAYED forces a refresh on the next QUEST_LOG_UPDATE.
_RegisterObjectiveTooltips: silently return for Type='event' objectives
with no spawnList (e.g. triggerEnd with nil coordinates). These have no
tooltip to register, so mark hasRegisteredTooltips=true and bail out.
For other types, demote from Error to Debug.
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.
