Use IsolatedAsyncioTestCase instead of async_test

Since we upgraded to Python 3.8, we can now use the new IsolatedAsyncioTestCase test class to use coroutine-based test methods instead of our own, custom async_test decorator. I have changed the base class for all of our test classes that use coroutine-based test methods and removed the now obsolete decorator from our helpers.
