WebSocket connections are not cleaned when ShoutBox is unmounted

[jjylik]

When the ShoutBox is mounted, it opens a new websocket connection which is never closed. You can see the following errors on console

Uncaught TypeError: Cannot read property 'scrollTo' of null

This can be reproduced by toggling the shoutbox a couple of times

A possible fix would be to close the websocket on unmount or lifting the ws connection to some parent component which is mounted only once
