myarts app | form_valid implementation suggestion

[LiorA1]

In the myarts/views.py module we can implement 'form_valid', in other manner, without to do a double 'save()' calls.

Thanks - this is a lot prettier and better from an OO perspective. I will make this change when I can update the course materials.
