38380566 Notifiy the default sms app when restoration is complete

* When the TelephonyBackupAgent is done restoring all the messages
from the backup file set, notify the default sms app with a null uri.
That triggers the sms app to do a full sync from the telephony db.

Test: Used the following manual steps to an initiate a restore:
adb shell bmgr list transports
adb shell bmgr transport android/com.android.internal.backup.LocalTransport
adb push ~/Downloads/com.android.providers.telephony /data/cache/backup/1/_full/com.android.providers.telephony
adb shell bmgr restore 1 com.android.providers.telephony
Then verified in the logs that:
1) The telephony restore triggered sending an intent to the default
sms app:
05-23 10:28:54.241  1711  5987 D SmsProvider: notifyIfNotDefaultSmsApp - called from null, notifying
2) The default sms app (bugle) received the intent:
05-23 10:28:54.271  4975  4975 V Bugle   : TelephonyChangeReceiver.onReceive Intent { act=android.provider.action.EXTERNAL_PROVIDER_CHANGE flg=0x20000010 cmp=com.google.android.apps.messaging/.shared.receiver.TelephonyChangeReceiver }
3) Bugle recognized the intent as one without a uri, hence triggering
a full sync:
05-23 10:28:54.273  4975  4995 I BugleDataModel: ProcessTelephonyChangeAction: external telephony provider change null
05-23 10:28:54.276  4975  4995 I BugleDataModel: ProcessTelephonyChangeAction: not single message change, force full sync
4) Verified in the app the messages were restored.
