test: squelch asyncio io warning

This silences the deprecation warning

     The 'asyncio_mode' default value will change to 'strict' in
     future, please explicitly use 'asyncio_mode=strict' or
     'asyncio_mode=auto' in pytest configuration file.

The difference is whether pytest considers async tests to be
asyncio-driven even when they are not marked @pytest.mark.asyncio
with 'auto' meaning yes, consider them even when not marked, and
'strict' requiring the marking.

This doesn't really make a difference for us, since we don't have
any async tests, but it's nevertheless nice to silence the warning.
