"[CreateProperty]" on nullable generic types causes compilation error when using a non-nullable type

Reproduction steps:
1. Open the attached “IN-120943” project
2. Observe the Console window

Expected result: Property bags are generated successfully without any compilation errors
Actual result: Compilation fails due to incorrect type being generated for the nullable generic property. Error: Cannot implicitly convert type 'bool?' to 'bool'. An explicit conversion exists (are you missing a cast?)
