* Helper to verify that the event loop was spun. As long as this is dispatched
* prior to a call to Close()/SpinningSynchronousClose() we are guaranteed this
* will be run if the event loop is spun to perform a close. This is because
* SpinningSynchronousClose must spin the event loop to realize the close
* completed and our runnable will already be enqueued and therefore run before
* the AsyncCloseConnection's callback. Note that this invariant may be
* violated if our runnables end up in different queues thanks to Quantum
* changes, so this test may need to be updated if the close dispatch changes.
