Deletion on Redirect should not 207

[jason-fox]

I have a redirect registration for all entities - Orion is just a wrapper:

{
    "type": "ContextSourceRegistration",
    "information": [
        {
            "entities": [
                {
                    "type": "*"
                }
            ]
        }
    ],
    "contextSourceInfo": [
        {
            "key": "jsonldContext",
            "value": "http://context/fixed-context.jsonld"
        },
        {
            "key": "Prefer",
            "value": "ngsi-ld=1.6"
        }
    ],
    "mode": "redirect",
    "operations": [
        "redirectionOps"
    ],
    "endpoint": "http://my-endpoint"
}

I delete a non-existent entity and Orion-LD returns a 207:

{
  "notUpdated": [
    {
      "statusCode": 404,
      "title": "Not Found",
      "detail": "urn:ngsi-ld:Xsara"
    },
    {
      "registrationId": "urn:ngsi-ld:ContextSourceRegistration:c326536a-f35a-11ef-ad05-0242ac140009",
      "statusCode": 404,
      "title": "Not Found"
    }
  ],
  "updated": []
}

However this is a REDIRECT - so we should not be checking locally - should just return a proxied 404.
