Application mode fails fatally when being shut down

Details

    Description

      The application mode fails fatally when being shut down (e.g. if the Dispatcher loses its leadership). The problem seems to be that the ApplicationDispatcherBootstrap cancels the applicationExecutionTask and applicationCompletionFuture that can trigger the execution of the fatal exception handler in the handler of the applicationCompletionFuture.

      I suggest to only call the fatal exception handler if an unexpected exception occurs in the applicationCompletionFuture callback.
