Event not emitted with all errors

[hmorey3]

Certain http errors are not causing the "record" event to be emitted, making my http recorder logic not run. For example, if I call a url that doesn't exist (and I would imagine timeouts). I would like to be able to record events like this for testing purposes

I believe this is because you are hooking into the node "response" event, which is probably not fired for errors in which there is no response, like timeouts. What do you think?

I think having an "error" event that you could subscribe to for timeouts etc would be very helpful! If you like to dig into it I'd be happy to review a PR
