[Settings] Settings within each SIM not been displayed to the user

The display of content is in majority depending on the callback result
of SIM card (in order to display the content).

However, to reduce the number of access of SubscriptionManager and
improve performance, a proxy has been design in between to reduce the
traffic and the latency required.

Within this situation, content didn't get displayed when Activity get
restarted since Proxy avoid to reduce the traffic through reducing the
callback to the Activity and even not generating request for update when
Activity resume.
