Saying you are stale in case of error is appropriate for the Scripted Thread
Plan runner plan. If the underlying Python code can't figure out what its
state is, it's likely in a bad way and we should mark it as stale and get rid
of it.
But these templates are more analogous to the base ThreadPlan than to the
scripted plan runner.
That one does:
virtual bool IsPlanStale() { return false; }
