setLightLocked() will update mColor. This will cause the led to not be turned off after the pulse. When notificationManager starts a attention pulse the led will be kept on. Since attention is of highest prio nothing can turn it off. This is fixed by resetting mColor back to 0 after the call. Change-Id: Id60ef96e5c21b47c23002f0bcf2fae7fb3f2ca10
