Make sure to enable uicc applications when SIM is inserted.

Upon setUiccApplicationsEnabled, we should notify al Phone objects of
the change, and Phone(GsmCdmaPhone) will re-evaluate whether they
need to enable or disable uicc applications.
Otherwise, if uicc apps are disabled, sub is inactive, and you can't
find a corresponding phone ID by getPhoneId(subId).

Bug: 154782458
Test: manual - disable and enable pSIM and makes sure it's enabled
back.
