mod_smacks: Skip hibernation logic if session was closed or replaced The resumption_token is removed when the session is closed via the pre-session-close event, signaling that it cannot be resumed, and therefore no hibernation timeout logic should be invoked. Fixes that if a session somehow is replaced by a new one using the same resource (which is the common behavior), the old session would still be around until it times out at which point it sends `<presence type="unavailable"/>` which would look as if it came from the new session, ie appearing offline to everyone including MUCs.
