Fix incorrect mapping to get subscriptioninfo

getActiveSubscriptionInfoList() returns a list of active subscription.
It doesn't 1:1 mapping with slotId. So it is not correct to use slotId
as index to get subscriptioninfo from list.
Use framework interface getActiveSubscriptionInfoForSimSlotIndex() to
get subscriptioninfo per slotid instead.
