Wrong 'this' destroyed when a server error is received

[robinsummerhill]

On receiving a server error frame an 'end' event handler is added to the incoming frame. Within this handler this refers to the incoming frame not the Client instance. The handler inadvertently calls destroy on the incoming frame and causes an uncaught exception.

destroy should be called on the Client instance to allow client code to attach an on('error', ....) handler.
