fix(libs): dot_dict custom implementation of __getattr__ lead to issue accessing build-in attribute

When running pytest --doctest-modules, it try to inspect if things are wrapper by accessing the '__wrapped__' attribute. Our custom implementation lead to KeyError in certain situation. Try the custom logic first, and fallback to super().__getattribute__ to prevent the issue and ensure more robust handling.
