Title: Fixes #351 and authCache Null Pointer exception

1) Fixes #351

2) SockJS socket closed event can be received just after a new socket when refreshing (F5) the client. The problem is that hitting F5 repeatedly makes a sessionID in authCache be removed twice in a row (or tried to), leading to a Null Pointer exception because Auth is already removed.
