[IMP] purchase : Decrease order quantity should not delete picking and moves

When deacreasing a quantity on a PO it will decrease the quantity
of an associated move. When the move's quantity reach 0, previously the
move was unlinked and aslo the picking if all moves inside were unlinked.

However the destination move(s) still exist with the quantity that has been
removed in the original move. It can confuse the end user which have a move without
origin.

This commit cancel the move/picking instead of unlink them. Thanks to this
the end user still have the link with the original moves and can guess from where
their destinations moves come from. It also remove the filter on PO in order
to display the canceled picking.
