tests: skip redirect test

seemingly, this test hits a fallback path for resolving access urls and
that fallback requires an API client; this issue may have started when
starlette (ASGI) framework switched from requests to httpx.

> So... the largest impact of this change will be for FastAPI devs.
They're the largest install base, they're using the test client, and the
change will introduce breaking changes into their test suites and
require extra work for their teams.

possible mitigations: upgrade fastapi, as per notes in notes in
