[FIX] stock_landed_costs: correct rounding tests

Previous forward-port (17b6191a02) includes
new tests (added by eb26694e0f) which are
now broken because quants with a cost of zero are forbidden.

Force a standard_price on created product to avoid this situation.
Adapt quants cost values.

Also change references of accounts and journals on records.
