[FIX] stock_account: validate invoice for product with non-reconcilable account

With Anglo-Saxon accounting, invoices with stock_moves on a product
having 'real_time' valuation cannot be validated: there is a user error
when the interim account is not reconcilable.

We modify _anglo_saxon_reconcile_valuation so that we do not try to reconcile
when the account is not reconcilable.
