Switching from not supplying on sale to supplying on sale for product should
not create a new purchase request::

    >>> inventory_line.product = changing_product
    >>> inventory_line.quantity = 100.0
    >>> inventory_line.expected_quantity = 0.0
    >>> inventory.save()
    >>> inventory.click('confirm')
    >>> inventory.state
    'done'
    >>> shipment.click('assign_try')
