ditto
There was a small bug in the exec test generator causing some nulls in batches to not be reset, due to iterating over the columns of the input tuple type rather than over all columns in the batch. Release note: None

I wonder if it would be better to make a new batch every time Next() is called. That way we don't need to worry about the batch being mutated by downstream operators, e.g. setting nulls or adding more columns.
