Handle IllegalStateException from TelephonyManager.

Some TelephonyManager APIs can throw an IllegalStateException; these
methods no longer exist in Master.  However, adding in exception handling
here to ensure crashes do not impact QT-based devices.
Note: This has already been fixed in AOSP and master, hence the
do not merge anywhere.

Test: Run telecom unit tests.
