CallLog: Fix improper call to SensitivePhoneNumbers

* isSensitiveNumber expects a subId to be passed, but with the current
  implementation gets a PhoneAccountHandle
* Actually pass the subId and make the call use an int, while on it
* Fall back to the default subId only when we get an
  INVALID_SUBSCRIPTION_ID
