Test no vibration if first ringer state = vibrate

Test to ensure when the device first boots up, that when the ringer
state on the volume dialog is set to VIBRATE, the device won't vibrate.
The device will only vibrate if the ringer is manually set to VIBRATE
later after initalization.

Test: atest VolumeDialogImplTest
