[SPARK-13536] [SQL] Missing Sort Attributes in Transform Clauses
#### What changes were proposed in this pull request?
When missing sort attributes are not in the output of `Transform`, we
should not bypass it and check its child nodes. Like `subquery`, we should not
continue finding the missing attributes in its child nodes.
#### How was this patch tested?
This is an internal code bug. So far, unable to trigger the external
behavior difference. The newly added code is just for covering and verifying it.
