Timeout fix

This is a fix for the timeout in Request.  Requests would timeout even after they succeeded.  With this method, when a Request times out it calls `:fail` then calls for `try_next_server!`.  This new method caused an issue where the Request no longer closed the connect because before everyone request "timed out" and called `try_next_server!` which has this at the top:
    def try_next_server!
        if @request
	    @request.close_connection
	    @request = nil
       end

so I added close_connection inside `:recieve_data`
