return events that don´t include any data

I'm not sure that I should return nil if eventType is not present. Please correct me if this is incorrect.

I belive we should not allow creation of Event without type & event_id (because of https://github.com/arkency/http_event_store/blob/master/lib/http_event_store/event.rb#L10)
That return nil seems to be a mistake for me - if we read something from store we should return it or raise an error if for some reason we are unable to parse the entry.

This spec depends on the return nil. I have never deleted an event from the event store so I'm not sure how this works and how to handle it.

For example what happens to a stream when a linked event´s original stream is deleted. Is the event ordering re-arranged?

Hmm maybe this does not make any sense - I would just raise an error - because what else we could do ?

I'm not sure if nil is good choice here - why not empty hash {} ?
