typing.TypedDict: unnecessary hasattr check

        if not hasattr(tp_dict, '__total__'):
            tp_dict.__total__ = total

go out of their way to account for the case there a TypedDict already has a __total__ attribute. But I don't think there is any way for the TypedDict to have that attribute at this point. For clarity, we should remove the check.
