ProductStoreCartAwareEvents: wrong check for website in setSessionProductStore (https://issues.apache.org/jira/browse/OFBIZ-4744). A patch from Michael Brohl: There's a duplicate check if the productStore is null instead of checking productStore and website in ProductStoreCartAwareEvents.setSessionProductStore.
