This commit fixes the following issues:
- The previous code does not handle the immediate transfer scenario when
auto_fill_qty_done is selected in the operation type. This raises a missing-record
error, trying to update qty_done on non-existing move line records.
- move._do_unreserve() keeps existing stock.move.line records if there is some
qty_done set, which is not a desirable outcome. All the linked move line records
should be unlinked before selected quants are assigned.
There are cases where auto-filling of qty_done of stock move line is not desirable.
e.g. you assign quants manually for some of the moves in a picking and not the others,
in such case you need to go over all the moves in the picking to either remove qty_done
or fill it in to proceed with the validation of the entire moves. Auto-fill behavior is
also troublesome when this function is used in a manufacturing order. i.e. having
qty_done of the component move live messes up the outcome of the production.
* Better layout
* Remove active_id dependency in some computed fields
* Clean code
* Refine constraint
* Take into account if the current line is previously reserved before clicking on the button.
