credits are not populated in prod data dump

[adenyes]

Credit elements are always empty in data dumps, though credits are populated in API.

andr00@Macrophage:check$ jq '.prods[0]|"\(.name) \(.credits)"' pouetdatadump-prods-20191204.json

Via API:

        "credits": [
            {
                "user": {
                    "id": "1199",

                },
                "role": "Code (additional)"
            },
            {

                },
                "role": "Graphics"
            },
            {
                "user": {
                    "id": "89030",
                    "nickname": "Lowlife",

                },
                "role": "Graphics"
            }
        ],

Expected: credit elements should be omitted or populated with data from DB.
