[SPARK-11803][SQL] fix Dataset self-join When we resolve the join operator, we may change the output of right side if self-join is detected. So in `Dataset.joinWith`, we should resolve the join operator first, and then get the left output and right output from it, instead of using `left.output` and `right.output` directly.
