After upgrading `pytest-asyncio` to the latest version, lots of tests started failing in CI only on Python 3.9: `RuntimeError: There is no current event loop in thread 'MainThread'` Apparently these tests may have only been passing previously due to issues in earlier versions of `pytest-asyncio`. Changing these tests to async seems to fix the failures on Python 3.9. Related issue: https://github.com/pytest-dev/pytest-asyncio/issues/1039
