[FIX] stock: delivery date cause fail in production scheduling

Create 3 items:

* FP
 ** manufactured from SFP
 ** reordering rule
 ** manufacture lead time 2 days
* SFP
 ** manufactured from CP
 ** reordering rule
 ** manufacture lead time 2 days
* CP
 ** buy from vendor
 ** reordering rule
 ** manufacture lead time 2 days

Create a sales quotation:
 * Product: FP
 * Delivery Date: +7 days from now
Save and confirm
Run scheduler.

No Manufacturing process will be started.
This occur because the reordering rule (orderpoint) check the
quantity needed at the current date + lead days, while the move
are being planned for the delivery date specified by
the user in the SO.
Moreover the quantities that depends on datetime.now() are not recomputed
so each scheduler run is failing to schedule new orders
