Title: Remove duplicate promotion_rules_helper

PromotionRulesHelper was duplicated across frontend and backend
* core/app/helpers/spree/promotion_rules_helper.rb
* backend/app/helpers/spree/promotion_rules_helper.rb

Since this is only used from spree_backend, this deletes the file in core and moves the spec into the backend.
