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.
