[IMP] mrp: add unbuild button on MO

In this commit:
- On done MO's form, add an Unbuild button, it would open a
wizard with the form view of an unbuild, and some pre-filled fields
such as MO, product, BOM, quantity and total quantity finished which
can be edited.
- In the unbuild order, improve the on_change of mo_id:
if the selected product is tracked by serial number,
set quantity to 1 by default and readonly
- Also clean the testcase of unbuild order.
