Hovering an NPC right after turning in one of its associated quests
spammed a debugstack trace in DEVELOP mode: the learner objective-
correlation block in GetTooltip called QuestLogCache.GetQuestObjectives
for a quest no longer in QuestLogCache (which gracefully returns {} but
logs the stack at line 306).
Guard the NPC and object correlation loops on
QuestiePlayer.currentQuestlog[questId] so live objective progress is only
looked up for quests the player is currently on. Not a crash and no
functional change for active quests.
