Modify TelephonyManager to expose sendEnvelopeWithStatus instead of sendEnvelope.

The RIL sendEnvelope command does not return the response from the SIM while
the sendEnvelopeWithStatus does. Since the response is required for certain
envelope commands, its better to expose sendEnvelopeWithStatus.
