Fix tooltip error for zone-complete trigger objectives (quest 50150)

_RegisterObjectiveTooltips was only silently skipping objectives
with Type == 'event'. Quest 50150 'Storm Peak Orders' uses a
server-tracked zone-completion trigger objective which has no spawnList
and no Id -- the server sends it with a type like 'monster' not 'event'.

Broaden the guard: any objective with no spawnList AND no Id has nothing
for Questie to draw. Mark hasRegisteredTooltips = true and return
silently. Objectives with no spawnList but a valid Id still error
so missing data is reported.
