Spawned tasks' phone is connected to spawning task

  • Only boot time tasks are connected to hardcoded NS task.
  • First connected phone of other tasks is connected to the task that spawned them (spawn parent).
  • Until further changes, effectively it changes nothing (NS was the ultimate spawn parent).
