[FIX] stock_account: reconcile kit

Kit were not reconcile because the `_stock_account_anglo_saxon_reconcile_valuation`
method try to match `account.move.line` and `stock.move` base on the
product field. However in kit case, the moves are exploded in mutliple
moves containing the kit's components. Due to that the matching is not
made.

To fix this issue we use the `purchase.order.line` that is share between
the `stock.move` and `account.move.line` to retrieve them.
