When someone set any wss server and do login
VC doesn't record the settings on localStorage,
so when we reload the browser, it will try to connect on
"wss://" + window.location.hostname + ":8082" and if
this wss server is offline for any reason, user will
be stuck on splash screen by auto-login step plus reconnect
modal blocking any action.

- Added button "Change Server" on modal reconnection alert;
- Stop jsonRpcClient retry timeout and delete verto instance
to create a new one when user login with new wss server;
- Record wss server and hostname on localStorage.
