bitbake: fix setscene task start/failure handling

* When a setscene task starts, print out that it's starting in the UI
  (ensuring we get the correct task name)
* When a setscene task fails, ensure we remove it from the list of
  running tasks so that if you break out any time afterwards it
  is not still listed.

(Bitbake rev: e8a3499c95a6d4f2b8fed002fb9504733c5be3c6)
