TEST-46-HOMED: Disable auth rate-limiting

Rate limiting authentication attempts in the test can cause somewhat
sporadic test failures: adding a test case might suddenly cause future
test cases to fail because of too many authentication attempts too
quickly

We're not trying to test the rate-limiting, we're trying to test the
functionality of homed. So we effectively disable rate-limiting on all
the home areas we create
