Initial failure of connect can result in 30 second hang

[anthonyvercolano]

If one gives a bad host address to connect with it will fail with an ENOTFOUND.

However, the connackTimer will have already been started.

Since the host was never opened we don't go through the close which along with the handleconnact to clear the timeout.

Suggest adding a clearTimout to the finish

@anthonyvercolano how is this going?

I have the same issue, running this in jest and providing the wrong address will cause it to hang even if I define a connectionTimeout.
