Using an abstract model which is also an abstract class.
In the subclass, I need to modify a field. This is done in the
__init_subclass__ method, by creating a field and adding it to the model
with ModelBase.add_to_class.
The field disappears from the class.
Doing exactly the same on a model which is not an abstract class works
fine.
see unittest file to reproduce this bug.
