Alerting: Fix TestRouteGetRuleStatuses as much as possible. (#86666)

This test has been skipped for a long time, so it doesn't work anymore. I've
fixed the test so it works again, but left some tests disabled which were
apparently flaky. If we see the other test cases flaking, we'll have to
disable it again.

Fixes:
- Use fake access control for most test cases, and real one for FGAC test cases.
- Check that "file" in API responses the full folder path, not folder title.
