Fix the bug in EventTimeTumblingWindow for non-partialMerge aggregate

    Details

      Description

      The row length used to initialize DataSetTumbleTimeWindowAggReduceGroupFunction was not set properly. (I think this is introduced by mistake when merging the code).
      We currently lack the built-in non-partial-merge Aggregates. Therefore this has not been captured by the unit test.

      Reproduce step:
      1. set the "supportPartial" to false for SumAggregate
      2. Then both testAllEventTimeTumblingWindowOverTime and testEventTimeTumblingGroupWindowOverTime will fail.
