Bug 24862: Regression tests

This patch introduces tests for the expected behaviour on API routes
that expect a logged in user, but the request is made with an anonymous
session cookie.

To test:
1. Apply this patch
2. Run:
   $ kshell
  k$ prove t/db_dependent/api/v1/auth_authenticate_api_request.t
=> FAIL: Tests fail because the situation is not handled correctly in
the code
