Instanced properties do not update in actors placed in a level that is not currently open

The user is specifically having a problem with TArray<TObjectPtr<>> however I have
also reproduced this error using a single TObjectPtr<>, raw uobject pointers & all three
previous methods within a USTRUCT property.

1. Open attached InstancedPropTest project in visual studio and compile
2. Open Level A
3. Place Actor in level A with an instanced TObjectPtr<> property.
4. Open the blueprint for the actor & change the default value for the property.
5. Move to level B.
6. Open the blueprint for actor & change the default value of the property to different value.
7. Return to Level A.
8. Check the actor that was placed in Level A, the property should be set to None.
