The more I looked at this test, the more I realized it wasn't testing anything except that the namespace parameter was being parsed by the websocket. So, I moved that parameter parsing check to `TestEventsSubscribe()`, which is not flaky, and removed the flaky test altogether. There is a similar set of tests in the enterprise repo that I will try to simplify and make less flaky, though.
