Title: get_session / set_session modifications (reviving deleted keys)

Actually, deleting keys form session wasn't working before. Session object in get_session and set_session are completely different objects, so passing hash through @old never worked (And I tried that with multiple rack versions). That is why it always were reviving deleted keys.
