When changing the demand quantity on a draft picking line or on a production order,
the related stock.move that should be in draft will be confirmed.
This is because the write function incorrectly calls _recompute_state on draft moves.
Also for mrp, using the split function on draft moves will mark the stock.moves of the new
production order(s) as confirmed because that's the only state given by _get_backorder_move_vals.
This is also fixed.
