Id and link properties in /<uuid>/parents endpoint is wrong

[Syndesi]

Example command:

curl http://localhost/45482998-274a-43d0-a466-f31d0b24cc0a/parents -H "Authorization: Bearer secret-token:PIPeJGUt7c00ENn8a5uDlc" | jq

Returns:

{
  "type": "_PartialCollection",
  "id": "/",
  "totalNodes": 1,
  "links": {
    "first": "/",
    "previous": null,
    "next": null,
    "last": "/"
  },
  "nodes": [],
  "relations": []
}

The links and id should contain the child's UUID.

/children and /related endpoints are affected as well.
