    hs-v3: Downgrade warning log when an intro circuit has closed
    
    When an intro circuit has closed, do not warn anymore when we can't find the
    service. It is possible to hit that condition if the service is removed before
    the circuits were fully closed. This happens in the case of deleting an
    ephemeral service.
