[FIX] sale_product_configurator: fix mobile product template search

Issue

	1. Install Sales
 	2. In the Sales settings activate "Product Configurator"
 	3. Create a product with variant set as "dynamic" (with dummy attributes)
 	4. Switch your browser view to the mobile view (using dev tools)
 	5. Click the order line "Add" button
 	6. Click on the product form
 	7. Search for your product of step 3.

	-> The product of step 3. does not shows up !

Cause

	The view used for mobile is the order_line form view in
	the view "view_order_form"

	This view uses product.product instead of product.template
	because the widget is not the same than the tree view.

Solution

	Use the product_configurator widget instead when
	the module is installed.
