Make existing tests use ``client_request fixture

This commit makes the existing tests around user permissions less
verbose by using the new `client_request` fixture.

This fixture takes care of:
- setting up a service
- asserting that the response is `200`

It also tests that the page titles, some of which didn’t match with the
`<h1>`s, so this commit also fixes that mismatch.
