Quick TIles: Remove Torch from static default list.
Make sure to turn off led after pulse()

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.
