Rollover: order line creation can fail because of validation

[PascalRepond]

Bug description:

The rollover can fail with following error "Order line creation failed on [acol#40765] :: Cannot create an order line with an order with a wrong status". This is because of a stricter validation on order line creation that checks the statuts of the linked order.

Expected behavior:

The rollover should complete without errors.

Probably change the rollover script so that it creates all orders with a PENDING status (allowing order lines to be added), and at the end attribute the correct status (ORDERED or PARTIALLY RECIEVED) to all orders based on their content.
