defaultCommandHandler bug, adding "undefined" to array of evtsToDispatch

[rakamoviz]

https://github.com/adrai/node-cqrs-domain/blob/4e70105b11a444b02c12f2850c61242b4998361c/lib/defaultCommandHandler.js#L896

There should be a check like this: rakamoviz@99fbc06 in order to avoid "undefined" getting pushed to evtsToDispatch

That happens when stream.eventsToDispatch is "undefined"; and stream.eventsToDispatch is "undefined" when you have eventPublisher attached to the eventstore: https://github.com/adrai/node-eventstore#async-interface

In theory yes. The question is, why it’s undefined?
Can you provide a PR that checks for an array?
