[REEF-1447] Validate Task close failure => FailedTask Event (task has not yet finished)

This addressed the issue by
  * Failing the Evaluator on an `Exception` in `TaskCloseHandler`.
  * Adding a test to test for close event failure while Task is still running. Validating that the `TaskCloseHandler` `Exception` triggers a `FailedEvaluator`.
  * Modify `TaskRuntime` and related tests to verify that the `TaskStopHandler` is not called upon `Task` failure.
