/core-model-1-4:network-control-domain=cache/link={uuid}/link-port={local-id} - error response message for unknown NEs needs to be changed

[kmohr-soprasteria]

If the cache doesn't contain data for the combination of uuid/local-id the service returns a 404 for both GET and DELETE, which is correct. However the responseMessages need to be modified, as they currently both return "unable to fetch records for link >uuid<".

They should be changed as follows:

• GET: "unable to fetch records for linkport >uuid</>local-id<"
• DELETE: "unable to delete records for linkport >uuid</>local-id<"
