Updated and renamed the DynamicClassAttribute tests, and discovered that classify_class_attrs is not handling instance portion correctly.

    class Meta(type):
        def __getattr__(self, name):
            if name == 'ham':
                return 'spam'
            return super().__getattr__(name)

    class VA(metaclass=Meta):
        @types.DynamicClassAttribute
        def ham(self):
            return 'eggs'

We should see both eggs and spam, but only eggs is showing up.
