Fix bug that disabled pSIM stays inactive after unplugging.

The expected behavior is, for inactive pSIMs, once unplugged, we
mark uicc applications back to true. In handleSimAbsent we failed to
do that as by clearing the subinfo with phoneId, as disabled subInfo
doesn't have phoneId associated with it already.
