Set up activate and deactivate on SIM state change.

Register for sim state changes so that a voicemail source can be added
and removed as appropriate:
- When a sim is added, send an activate sms. (the received status sms is
  processed in OmtpMessageReceiver)
- When a sim is removed, remove the corresponding sync account and
  change the status in the voicemail status table to not configured.
