Detect cider-disconnect, close listen-socket

[the-kenny]

If you have a weasel-repl open and kill emacs (or close the repl buffer) then the listen-socket for the websocket connection stays open, leading to a BindException: Address already in use.

A new weasel-repl should either use an already existing socket (if that's possible) or close other ones automatically.

If #51 implements close-on-disconnect we could implement it for the other direction too.
