swarming: fix invalid events on task retry

When a TaskRunResult failed with an internal error but the TaskResultSummary is
still PENDING/RUNNING, an event would be sent which would eventually lead to an
error like:
  Unhandled task state 16

Check the summary result, not the run result, for completion.
