    [FLINK-23528][datastream] Let CollectSinkOperator publish results in #close.
    
    DataStream#executeAndCollect expects the CollectSinkOperator to register the accumulator at the end of the application or fails with some exception.
    However, a stop-with-savepoint without drain would not trigger CollectSinkOperator#finish and thus skip the registration.
