Schema composer forgets inheritance selection on redefined types

[Geert Bellekens]

Details:
When building a schema you can select whether or not to include the generalizations on a redefined type.
This information however is not stored in the database and lost upon reloading the schema


Steps to Reproduce:
- create a schema with the schema composer
- add an element that has a generalization to another class
- create a redefined type for that element in the schema composer
- select the inheritance checkbox on the redefined type.
- save the schema
- reload the schema
- notice that the inheritance checkbox for the redefined type is now unchecked.
