Fix search indexed the item from the invisible sim

When search start to index and run to MobileNetworkSettings.java, the
TelephonyBasePreferenceController will find which subId can be the
"AVAILABLE" from the active subscriptionInfo list. This active subscriptionInfo
list does not be filtered, so the search uses the invisibile sim's item for user.
