Assume any arguments typed `None` are `Optional[Any]` instead. #70

We've had a few instances where pyannotate marks a keyword argument as having type None since it hadn't observed any instances of that value being passed in, but none of those instances have been correct. It would be safer to assume the type is Optional[Any].

Thanks! Good idea.
