Refactor Order#current_order extension

[HugsDaniel]

Description

In Spree 2.0, Order#current_order takes a hash as argument.

Current status

In lib/spree/core/controller_helpers/order_decorator.rb we extend Spree's current_order like this :

def current_order_with_scoped_variants(create_order_if_necessary = false)
    order = current_order_without_scoped_variants(create_order_if_necessary)

    if order
      scoper = OpenFoodNetwork::ScopeVariantToHub.new(order.distributor)
      order.line_items.each do |li|
        scoper.scope(li.variant)
      end
    end

  order
end

And in Spree :

def current_order(create_order_if_necessary = false)
  ....
end

How does it look in Spree 2.0 ?

In Spree 2.0, Order#current_order now takes a hash of options :

def current_order(options = {})
   options[:create_order_if_necessary] ||= false
   options[:lock] ||= false
    ....
end

So we need to change the params we send in our extension.
