Default subobjects do not get PostLoad called

PostLoad function is not called for blueprint components added through code.

Regression: Yes

In 4.12.5 (CL 3039270) code components do have PostLoad called if other components are not added through the editor
in 4.13.2 (CL 3172292) code components do not have PostLoad called in any circumstance.

1. Open UE4 Editor (any project)
2. Add code to project based on Actor (MyActor)
3. Add the following to MyActor.h

   UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = Test)
   	UStaticMeshComponent* MyMesh;
   

4. Add the followind to MyActor.cpp constructor

   MyMesh = CreateDefaultSubobject<UStaticMeshComponent>(TEXT("MyMesh"));
   	RootComponent = MyMesh;
   

5. Compile
6. Add two blueprints based on MyActor (Positive and Negative)
7. Open Negative blueprint and add Scene component
8. Save and close the editor
9. Launch the editor through Visual studio
10. Place Breakpoint in UStaticMeshComponent::PostLoad() function
11. Double click Positive to open blueprint
12. Double Click Negative to open blueprint

Result:
In 4.12, opening Positive will trigger breakpoint but opening Negative does not. In 4.13 and 4.14, nether Positive nor Negative trigger breakpoint

Expected:
PostLoad is called for all components regardless of the other components in a blueprint.
