[FIX] stock: move line: write

Write is overridden on reserved move lines to make sure the quants are
correctly updated. It is divided in two parts: if you update the reserved
quantity and if you update a characteristic. If somehow both are updated
in the same call (which doesn't happen in the standard interface), then
the quants are unreserved two times, which is wrong.

This issue showcased by [0] and on databases where the reserved
quantities are made editable by customization.

We grouped the two update in one, such as the TODO indicated us since a
long, long time.
We removed `result_packaged_id` from the trigger because it should not
impact the reservation whatsoever.
We needed to remove a tricky logic in the stock move's backordering part
but it was fishy anyway.
