Clean up Gitaly tests

See merge request !12526

- Rather than using an explicit check to turn off authentication for the
  `/users` endpoint, simply call `authenticate_non_get!`.

- All `GET` endpoints we wish to restrict already call
  `authenticated_as_admin!`, and so remain inacessible to anonymous users.

- This _does_ open up the `/users/:id` endpoint to anonymous access. It contains
  the same access check that `/users` users, and so is safe for use here.

- More context: https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/12445#note_34031323

Also, using page.current_path instead of current_url and move the URL
expectation after the page content expectations.
