Describe the bug

When deploying Hydra and it does not have any clients yet. doing a API Call to getClients will always respod with response that has a Link header in which rel="next" is always present. Meaning if API client is utilizing the contract and doing calls to get all clients from all pages, it will stuck to infinite loop because next page rel link will always be present

Reproducing the bug

1. On virgin Hydra with empty database do an API call to get Oauth2 clients, with let's say page size 10 and page token "1" as first page token.

Expected result:
Considering there are not any clients response should contain Link header without rel="next"

Actual result:
Response contains Link header with rel="next" and every next call to this next page with this token returns again empty page and again rel="next" in Link header containing token to next empty page, never ending.

Relevant log output

Example of Link header while no any single client exists:
</admin/clients?page_size=250&page_token=eyJvZmZzZXQiOiIwIiwidiI6Mn0>; rel="first",</admin/clients?page_size=250&page_token=eyJvZmZzZXQiOiIyNTAiLCJ2IjoyfQ>; rel="next",</admin/clients?page_size=250&page_token=eyJvZmZzZXQiOiItMjUwIiwidiI6Mn0>; rel="prev"
