FBlueprintCompileReinstancer::ReplaceInstancesOfClass_Inner() can fail to resolve reinstanced archetypes.

From UDN.

This is a hotreload bug - even though it uses FBlueprintCompileReinstancer.

1. Make two classes: ClassA and ClassB
2. ClassB should contain an instanced property of type ClassA and an instance of ClassB

In QAGame:

1. Start QAGame Editor
2. Place an instance of QA_SubobjectTest (QA Subobject Test if found via the placement menu)
3. Add a property to both QASubobjectTest and UQASubobject:

UPROPERTY(EditAnywhere, Category = "Default Subobject Testing")
bool Neat;

1. Click the compile button in the editor, note ensure when reinstancing occurs
