Fix error activating drawing style

Example error:
```
TypeError: bpy_struct: item.attr = val: enum "Default" not found in ('city.exr', 'courtyard.exr', 'forest.exr', 'interior.exr', 'night.exr', 'studio.exr', 'sunrise.exr', 'sunset.exr')
```

There was a bug in shading_styles.json where we were using `Default` for `studio_light`, which is only available for `SOLID` shading type. Changed value to `forest.exr`, added code to handle old bugged value since users already copied and possibly modified shading_styles.json
