Component name conflict when reparenting from a blueprint parent to a native parent causes data loss and component pointer to be null.

Reparenting a blueprint from a blueprint to a native class will cause data loss if both parents have a component with the same name. The component ptr will always be null after reparenting. Expected result: reparenting maps component data from original parent to new parent. 

1. Create an actor blueprint named "BP_Parent"
2. Add a Box component named "Box" to BP_Parent
3. Compile and save BP_Parent
4. Create a child blueprint deriving from BP_Parent named "BP_Child"
5. Compile and save BP_Child
6. Create a native class derived from AActor named "ANativeParent"
7. Add a UBoxComponent* variable named "Box". Mark up as a UPROPERTY
8. In ANativeParent's constructor, create a UBoxComponent using CreateDefaultSubobject and point the Box pointer at it. Box = CreateDefaultSubobject<UBoxComponent>(TEXT("Box"));
9. Save and compile the project
10. Reparent BP_Child from BP_Parent to NativeParent
11. Compile BP_Child and check the Box variable after BeginPlay and Box will be a nullptr.
