Example: 'async_generator' object has no attribute 'server_info' error

Hello,

So I wanted to try motor, thus was looking at this repo and unfortunately after running the example I received following error:

Besides AttributeError: 'async_generator' object has no attribute 'server_info' I wonder why these 2 warnings pop up.

Any guidance in understanding this issue is appreciated.
