Un-handled exception in unsubscribe() remote service.

[ralemy]

Thank you for sharing this library.

The http.request() made in unsubscribe() function, line 596 does not have a handler for error function. this means that if the remote device shuts down before the peer, there will be an un-handled exception when the local peer tries to shut down, and calls removeAllListeners().

It would be great if line 615 would have the following code:
req.on("error",function(){});
