Throw errors when operating on destroyed wrapper

[xanf]

A bit related to #1342

While it is obviously impossible to "destroy" something in JavaScript it could be great help to make wrappers throw error when operating on destroyed Vue instance. I suggest making emitted (and deprecated emittedByOrder) the only exceptions, cause I can see use cases, when we want to assert instance generated certain events during destroy process.

This will help a lot when introducing enableAutoDestroy(beforeEach) in big codebases to track such hard-to-debug errors
I'm ready to submit PR for this one if team feels this one like a good addition

Hi! I understand why this would become useful when running enableAutoDestroy, feel free to submit the PR :)
