Wrong product_template changed when changing UOM for product

Created by: diggy128

In product_uom_update module, when trying to change a product's UOM, the query feeds the id from product_product though the table changed is product_template so, in line 69 in product_uom_update should be:

-                    product_ids_validate.append(dst_product_id.id)
+                    product_ids_validate.append(dst_product_id.product_tmpl_id.id)
