loop_scope="package" raises a fixture not found error

[NoahStapp]

When using loop_scope="package", this fixture defined in my test/asynchronous/conftest.py throws a fatal error on test setup:

@pytest_asyncio.fixture(loop_scope="package", scope="package", autouse=True)
async def test_setup_and_teardown():
    await async_setup()
    yield
    await async_teardown()

# Error:
E       fixture 'test/asynchronous::<event_loop>' not found

Every other loop_scope does not throw this error. Is there an additional step required for package scoped fixtures?
