Property Redirectors do not update the DisplayName of delegate nodes

This is happening because the property 
FText DelegatePropertyDisplayName;
on UK2Node_ComponentBoundEvent is serialized, so it does not get properly updated. 

1. Create a native class (FooActor) that override Actor
2. Add a delegate UPROPERTY with a display name set
3. Override this class in BP and add a call to this delegate
4. Close the editor, and change the display name of the delegate property
5. Add a property redirector in the  [CoreRedirects]section of DefaultEngine.ini
6. Restart the editor, notice that the display name of the event is not updated
