tokel with websockets support: js client does not disconnect from localhost ws node

[dimxy]

A javascript nodejs client connected to a local websockets tokel daemon node does not properly disconnect:
after client end getwspeers still shows the js client in the list
daemon console shows a error: [info] Error getting remote endpoint: system:22 (Invalid argument)
This does not happen when a client disconnects from a remote linux daemon
Also a js client disconnects okay from a non-ws daemon node.
That is, the issue is possibly in websocketspp lib or its usage by the daemon code
Currently disconnect in js is done by a call to socket.end() and there is an event to catch 'close' (so it is not an early client app finish). I also tried to use socket.socket.close() call for the js websocket object but this also did not help
