fix(test): use function scope for asyncio test loop

We were configuring a module-level loop, but had @pytest_asyncio.fixture
without a scope, with the intention of being function scope. This is now
triggers an error with pytest-asyncio.

Following advice of https://pytest-asyncio.readthedocs.io/en/stable/how-to-guides/migrate_from_0_23.html
we now explicitly set the asyncio_default_fixture_loop_scope pytest
option to "function".
