Add a RoutesProxy so that we can do things like spree_core.root_path in Cucumber features
user
```ruby
module NavigationHelpers
  class RoutesProxy
    include Rails.application.routes.url_helpers
  end

  def spree_core
    ActionDispatch::Routing::RoutesProxy.new(Spree::Core::Engine.routes, RoutesProxy.new)
