Spree::ProductDuplicator bug on price

[Roddoric]

Summary

Created to support #4970

Until v3.2.3 duplicating a product duplicated the price.
Since v3.2.4 the product duplication does not duplicate the price.

Looks like it comes from the PR #4639 :/

The code looks like price is supposed to be copied:
Spree::ProductDuplicator#duplicate_master

    def duplicate_master
      master = product.master
      master.dup.tap do |new_master|
        new_master.sku = "COPY OF #{master.sku}"
        new_master.deleted_at = nil
        new_master.images = master.images.map { |image| duplicate_image image } if @include_images
        new_master.price = master.price
      end
    end

To fix it I duplicated all of the master prices on the new_product.master.
Looks like it work for the test and for our app.

[Roddoric]

@kennyadsl it should also be back-ported to v3.1 as the version 3.1.9 is also concerned
