Fix ghosts throwing exception on round restart.

Done by re-organizing the cleanup sequence so that players are moved back to lobby and have their mind wiped *before* entities are deleted.

The mind system always tries to ensure players have a ghost even in the most wacky circumstances like entity deletion. This goes contrary to the fact that we need to delete all entities to clean the game state. So cleaning all the minds should be done first.
