Fix PytestUnknownMarkWarning and RuntimeWarning in CI (#1228) (#1229)

- Register 'integration' pytest mark in pyproject.toml
- Fix unawaited coroutine in test_new_conn_passes_timeout_to_multistream_client
  by using assert_called_once() and call_args instead of calling the AsyncMock again
- Add newsfragment 1228.bugfix.rst
