build: Tweak exception handling for setscene tasksyocto-3.4.32021-10.3-honister1.52.3

If an unexpected exception occurs in a setscene task, it is currently hidden
from the user and not recorded in any logs. This isn't helpful to debug
such failures.

Change the code so that even in the "silent" or "quiet" task case (setscene
tasks), a warning is shown with the traceback unless it was an "handled"
exception. This means the failing function can show it's own warning/error
instead if it wants to and then raise a handled event.
