REVISION SUMMARY
  After commit b13453360685 <https://phabricator.kde.org/R293:b134533606857226afa067a814999790b868c3f1> ("Use flag to track when a runner is going idle")
  the scheduler may be triggered from the finished content indexer thread,
  picking up any remaining work and overwriting the "Suspended" state.
  
  Use a flag variable for the suspend state, and determine the current
  state in the scheduler loop, like it is done for e.g. the onBattery
  state.

TEST PLAN
  feed some files into the content indexer
  suspend using `balooctl suspend`, content indexer stops and stays stopped
