FComponentReference loses its actor reference when the target actor is reinstanced

The "OtherActor" pointer in an FComponentReference is invalidated when the referenced actor is reinstanced after compilation.

• Create two actor Blueprints BP_Referencer and BP_Target.
• Add a component to BP_Target using the Blueprint Editor.
• Add an FComponentReference property to BP_Referencer and make it public.
• Drag an instance of each Blueprint into the level.
• Set the FcomponentReference property in the BP_Referencer instance to point at a component in the BP_Target instance.
• Compile BP_Target and note the the "OtherActor" object pointer in BP_Referencer is set to None.
