DoNotCreateDefaultSubobject is not recognized when an actor is duplicated

Adding DoNotCreateDefaultSubobject to a class after placing an instance of that class in the viewport will fail to be recognized when duplicating the placed instance. This is not a hot reload issue, behavior also occurs if the editor is closed when compiling.

Regression:
No- Behavior also occurs in 4.14.3 binary (CL 3249277)

1. Open UE4 Editor (any project)
2. Add code to project based on Player Start (MyPlayerStart)
3. Add the following code to MyPlayerStart.h

   public:
   	AMyPlayerStart(const FObjectInitializer& ObjectInitializer)
   		: Super(ObjectInitializer.DoNotCreateDefaultSubobject("Arrow")) {    }
   

4. Compile
5. Add instance of MyPlayerStart to the viewport
6. Save and close the editor
7. Change Super(ObjectInitializer) to Super(ObjectInitializer.DoNotCreateDefaultSubobject("Arrow"))
8. Compile
9. Restart the editor (note arrow is missing from placed instance)
10. Select placed instance of MyPlayerStart
11. Ctrl+W to duplicate the instance then deselect it

Result:
Duplicated copy still have arrow component showing

Expected:
Duplicated instance follows code rule of not creating default components when set
