Issue #1970482 by rszrama, davidwthomas: fix the regression introduced by #1863776 into commerce_product_reference_commerce_product_uri() that prevented product image / file fields from linking to the entity into whose display they were being injected; specifically this makes injected product image fields able to link to the product displays that reference them again.
