fix the issue that update carrier id to the wrong subId during switch

This happens during profile switch. carrier id identification
logic listens for recordsLoaded which triggered before subId update.
so we updated the new carrier id to the old subId (subId doesnt change
to -1 during profile update). The fix is having a single entry point
to trigger carrier identification which is from subscriptionInfoUpdater
when subId update finished.
