[IMP] sale: remove duplicate codes for price_total

The price_total field (computed) on the account.move.line model in the account module is overrid
in the sale module with a new compute method doing exactly the same thing. This override is
useless and leads to a duplicate field on the database making the ORM slower and providing
unecessary work for the migration team.
