remove duplicate backend migration prompts
The duplicate prompts can be confusing when the user confirms that a migration should happen and we immediately prompt a second time for the same thing with slightly different wording. The extra hand-holding that this provides for legacy remote states is less critical now, since it's been 2 major release cycles since those were removed.
