[FIX] pos_restaurant: Error when adding product after printing the bill

Issue

	- Install "Point of sale"
	- Create a new one.
	- Activate the "Is a Bar/Restaurant" feature and save
	- Activate the "Bill Printing" feature then save
	- Start a new session
	- Add a product A
	- Click on "Bill" then "Print"
	- Then click on "Ok" to go back to order
	- Add a product B

	Error is raised ("Cannot read property 'add_product' of null").

Cause

	Trying to add a product to an order who is destroyed
	if the bill has been printed.

Solution

	If the bill is printed (and not the receipt), set '_printed' of
	the current order to 'false', therefore it will add the product
	to the current order.
