ScopedEventBus serializable problem

[Emmenemoi]

ListenerCollection implements Serializable but not WeakHashMap. As a consequence ListenerCollection is NOT Serializable because of weakListeners property.

Would it be a solution ?

@peholmst Hey Petter, is your side project applicable for BFP? We currently ran into the same issue using your eventbus addon in one of our applications (V8 + addon 2-0-0).

I'll add a pull request, the idea is here but it needs testing
