Clean up Icc Refresh handling.

1. When a SIM refresh is received of type INIT or RESET,
don't immediately start re-fetching the records, because
the app might not be ready. In this case, we could end up
broadcasting that all records are loaded pre-maturely.

On a refresh of the above type, the app will move out of the
ready state and back into the PIN state, if PIN is enabled.
Start reading the records only after the PIN has been verified
and the app has moved to the READY state.

2. UiccController will listen for refresh and propagate it to
the Card and the Apps. The App will set its state to UNKNOWN
on receiving a refresh.
UiccController will also request card status on receiving
refresh to get the latest state.

This avoids having to make assumptions on the ordering of the
Unsols for Sim Refresh and card state changes. This also
ensures that after an app state is marked UNKNOWN,
it will move to READY, if it is truly ready.

3. Moved common implementation for refresh into IccRecords
for better code reuse.

4. Side effect of #3 is RuimRecords will now reset AdnCache when
refresh of type INIT is received.
