PriceTaxCalculator: für Items berechnete flüchtige Werte zurückgeben Teil 3

Die items können nicht als Hash-Referenz gespeichert werden, weil das
kaputt geht, wenn die Items noch nicht gespeichert wurden und damit noch
keine ID besitzen. Daher Umstellung auf Array-Speicherung.

Außerdem Anpassung des Testcases.
