The default value for a property is saved as an override when ApplyModifiedProperties is called after changing a value on a property of a variant in the Hierarchy

How to reproduce:
1. Open the attached project “PrefabVariantDefaultValue.zip“
2. Open Scene “SampleScene”
3. Select “TestPrefab0” in the Hierarchy
4. Press “Modify Original” button in the Inspector
5. Select “VariantChild” (child GameObject of TestPrefabVariant0) in the Hierarchy
6. Press “Modify Original” button in the Inspector
7. Save the Scene
8. Open "TestPrefab Variant.prefab" in the Assets folder
9. Observe the “Test Value 0” property

Expected result: The “Test Value 0” property is not marked as an override in the Inspector
Actual result: The “Test Value 0” property is marked as an override in the Inspector
