Better handling of one time products in order-based projects

One time products will now be handled much better in smart order-based projects.

From now on any product that is set to a ship once frequency will be marked as owned as soon as the order for it is generated. Previously we kept these products shown as active in Firmhouse Portal and Firmhouse Self Service Center which is could lead to confusion for your customer.

In addition, this fixes an issue that Shopify sometimes returned the wrong shipping costs for a recurring order, because it was still treating previous ship once products as active.
