Fix widget test failure: prevent name field addition to default configs

- Modified _on_config_name_change to only add 'name' field to non-default configs
- This prevents DEFAULT_CONFIGS from being modified during widget initialization
- Ensures test_no_name_description_in_default_configs passes correctly
- All 306 tests now passing
