Regression preventing non python pytest test items

[RobertCraigie]

In v0.17.1 the pytest_runtest_setup function was modified from:

...
if (
    item.get_closest_marker("asyncio") is not None
    and not getattr(item.obj, "hypothesis", False)
    and getattr(item.obj, "is_hypothesis_test", False)
):
    ...

To this:

...
obj = item.obj  # type: ignore[attr-defined]
if (
    item.get_closest_marker("asyncio") is not None
    and not getattr(obj, "hypothesis", False)
    and getattr(obj, "is_hypothesis_test", False)
):
    ...

Which will then cause an error when non-python test items are collected, for example this CI run: https://github.com/RobertCraigie/prisma-client-py/runs/4835031754?check_suite_focus=true

item = <PyrightTestItem count.py>

    def pytest_runtest_setup(item: pytest.Item) -> None:
        if "asyncio" in item.keywords:
            fixturenames = item.fixturenames  # type: ignore[attr-defined]
            # inject an event loop fixture for all async tests
            if "event_loop" in fixturenames:
                fixturenames.remove("event_loop")
            fixturenames.insert(0, "event_loop")
>       obj = item.obj  # type: ignore[attr-defined]
E       AttributeError: 'PyrightTestItem' object has no attribute 'obj'

/tmp/tox/prisma-client-py/typesafety-pyright/lib/python3.9/site-packages/pytest_asyncio/plugin.py:450: AttributeError

It should be noted that these custom pytest items have no interaction with pytest-asyncio, they are simply collected while the pytest-asyncio plugin is installed.
