morphia: Cascading Generics are not correctly mapped

Describe the bug Similar to https://github.com/MorphiaOrg/morphia/issues/1481

When having cascaded generics the type is not correctly mapped.

To Reproduce See code example under Additional context

Expected behavior UUID is mapped to UUID instead of Binary

• Server Version: 4.0.17
• Driver Version: 4.0.5
• Morphia Version: 2.0.1
