Remove unnecessary call to `/api/v4`

When the provider is created (observed during acceptance tests) it makes the following HTTP request:

==> GET /api/v4/
    TRANS-ID: 585d868d-e4b6-c788-c80f-bd6c1284cb5b at 2022-12-19T17:41:21.751350+01:00
    HTTP BODY:
<== 404 Not Found
    TRANS-ID: 585d868d-e4b6-c788-c80f-bd6c1284cb5b at 2022-12-19T17:41:21.944437+01:00
    HTTP BODY:
    {
      "error": "404 Not Found"
    }

... which seems odd and unnecessary.

Lets get rid of it or at least have justification why it's necessary.
