[FIX] mrp: more Voodoo magic

It appears that if you update a record more than once in the same
PostgreSQL transaction, PostgreSQL is going to re-check all the
constraints on the table.

** THIS IS THE PART WHERE THE BLACK MAGIC HAPPENS **

We combine the setting of the default value of stock.move.unit_factor in
the same UPDATE query to avoid the constraint re-check; it saves
approximately 60% of the SQL running time in my case.

** ... AND NOW YOU CAN SAY: WHAT THE F...?! **

Thanks to @rco-odoo for the tip; he knows it from the wise @nseinlet.
