Description

Currently KeyRange.intersect(KeyRange range) returning EMPTY_RANGE only when the left side key range is null and right side is not null but we should return EMPTY_RANGE when any of the key range is null.

        if (this == IS_NULL_RANGE) {
            if (range == IS_NULL_RANGE) {
                 return IS_NULL_RANGE;
            }
             return EMPTY_RANGE;
         }
