[FIX] stock: barckorder on move with mulitple move_line

When a move is set to done and a backorder should be create, we get a
traceback saying that we cannot set the quantity done on a move with
multiple move move_lines.

This occurs, when the stock move has multiple move lines with quantity
done set to 0;

Because the new move only contains move lines having quantity done 0, we
remove the useless line that set the quantity done on the move
