RESTful services: return "404 Not Found" instead "503 Service Unavailable" if referenced Archive AE is not configured

[gunterze]

Rational: 503 Service Unavailable indicates a temporary overload or scheduled maintenance, which will likely be alleviated after some delay - which is not the case if the referenced Archive AE is not configured
