 ### Changed
 * Hosts now delete their lobby when shutting down instead of only leaving it (#772) Since Boss Room doesn't support host migration, there is no need to keep the lobby alive after the host shuts down. This also changes how LobbyServiceExceptions are handled to prevent popup messages on clients trying to leave a lobby that is already deleted, following the best practices outlined in this doc : https://docs.unity.com/lobby/delete-a-lobby.html
