Re-joining and joining a new game doesn't work

[vaslabs]

• There's a weird behaviour when a user:
  1. quits and joins a new game
  2. quits and rejoins the game

The websocket connections are not given back. It could be that quitting actually removes the player to a point of no recovery but that's just a guess. There are no messages coming back from the websocket even though it's connected which could indicate either the guardian crashing or the actor player dying. There are also dead letters when this happens
