Components copy/pasted from an actor instance's SCS can't be deleted from a Blueprint

SCS added components pasted from an actor instance in the level editor cannot be deleted from the target Blueprint because the component template has the RF_ArchetypeObject flag.

• Add an actor to the level
• Add a StaticMeshComponent to the actor instance via the details panel/instance subobject editor
• Copy the static mesh component
• Paste the static mesh component onto a Blueprint's root component using the BP editor's subobject editor and compile
• Note that the pasted component has the RF_ArchetypeObject flag and can't be deleted from the hierarchy
