Fix upgrade from subId to iccId use in PhoneAccount id.

Because the defaultUserSelectedPhoneAccount is based on a
PhoneAccountHandle that use to use the subId and now uses the iccId of
the phone, the default phone account is lost when upgrading from LMP to
MNC. This bug will handle that upgrade step so that the default phone
account setting is not lost.
