Fixed issue with Indicator when plugging/unplugging charger

RequestUpdate()
Update thread wakes up in UpdateRenderReady()
* update & render *
* Indicator is updated *
RequestUpdateOnce()
   IsUpdateRenderThreadPaused() returns false
ProcessSleepRequest()
Update thread sleeps in UpdateRenderReady()

In other words we're sleeping too soon, before the Indicator has been rendered.
This is more likely to occur on mobile, since we get spammed with damage events.
