Apply only RING_VIBRATION_INTENSITY to ringtone vibrations

Ignore the VIBRATE_WHEN_RINGING deprecated settings for ring vibrations.
Old behavior applied this settings only to ringer-mode normal, but never
to vibrate-only ringer mode.

This is being deprecated in favor of the INTENSITY_OFF value in
RING_VIBRATION_INTENSITY.
