add error for /summon with wrong entity event

(Bedrock edition)

When summoning an entity with an entity event it would be nice if there would be an error when you try to summon an entity with an event that is not in its entity.json file.

When you try to use an event from the pig.json on a sheep with the /event command, it gives you an error saying that the event is not possible for sheep. When summoning an entity with an event, the same should happen.
