Manual merge: Update VIBRATE_ON to a supported value when upgrading from GB.

Bug: 5738552

If value has ringer set to VIBRATE_OFF, we need to update it to the
now default, as VIBRATE_OFF is inconsistent with the new UI controls.

Make sure notification vibrate setting follows ringer vibrate setting.
