fix: Fixed incorrect concrete types used for creating generic scriptable objects

Concrete types that do not derive directly from the requested generic type were used to create a generic scriptable object. This behaviour was incorrect and an additional check was introduced that checks if the concrete type derives directly from the generic type.
