[FIX] stock_landed_costs: enable and adapt forgotten tests

stock_landed_costs.yml is adapted to validate the picking before
applying a landed cost on there. Applying a landed cost on a non
validated picking was never supported but the test fails due to
implementation changes in v11.

Due to this change, the last assert was wrong: indeed, applying a landed
cost on a delivered product creates 6 account move lines if anglo saxon
accounting is enabled. This case creates 4 landed costs on 2 delivered
stock moves, 4*2*6 == 48 account move lines.
