py-test-asyncio: updated to 0.12.0

0.12.0:
Run the event loop fixture as soon as possible. This helps with fixtures that \ 
have an implicit dependency on the event loop.

0.11.0:
Test on 3.8, drop 3.3 and 3.4. Stick to 0.10 for these versions.
Use the new Pytest 5.4.0 Function API. We therefore depend on pytest >= 5.4.0.
Better pytest.skip support.
