[pyup-bot]

This PR updates pytest-aiohttp from 0.3.0 to 1.0.1.

Changelog

1.0.1

------------------

- Don't implicitly switch from legacy to auto asyncio_mode, the integration doesn't work
well.

1.0.0

------------------

- The plugin is compatible with ``pytest-asyncio`` now.  It uses ``pytest-asyncio`` for
async tests running and async fixtures support, providing by itself only fixtures for
creating aiohttp test server and client.
