Code generator does not find class duplicates in subobjects

[MatPoppFHG]

If two Categories have subobjects with the same title, the code generator will create only one pydantic class => an arror will occur in the (sub) class which has not been created

Possible solution(s):

• add prefixes or suffixes for subclass definition names.
• ceck by uuid if parent objects are the same or not.
