Close connection from server-side

[clarkk]

If you close the connection from the ServerHandler you get an error

	public function onMessage(ConnectionContract $conn, $msg){
		$socket_id 		= $conn->getUniqueSocketId();
		$json 			= json_decode($msg, true);
		
		if(empty($json['sid'])){
			$conn->close();
		}
	}

error
