Fix tooltip objective population error for event-type objectives with no spawnList

_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.
