Daniel Nephin 8b365f8271 Remove a racy and failing test
This test is super racy (it's not just a single line).

This test also starts failing once streaming is enabled, because the
cache rate limit no longer applies to the requests in the test. The
queries use streaming instead of the cache.

This test is no longer valid, and the functionality is already well
tested by TestCacheThrottle.  Instead of spending time rewriting this
test, let's remove it.

```
