This patch clears all sliding sync room subscriptions when a session expires. Indeed, we might not want to request all room subscriptions when the session restarts. Imagine if the client has subscribed to 400 rooms and the session expires: once the session restarts, it will ask for 400 room subscriptions, which is a lot and will result in a quite slow response.
