[SPARK-21538][SQL] Fix attribute resolution inconsistency in Dataset API

[viirya]

What changes were proposed in this pull request?

Given a string column name, the following operation fails with an AnalysisException:

spark.range(1).withColumnRenamed("id", "x").sort("id")

However, the other APIs work:

spark.range(1).withColumnRenamed("id", "x").sort(col("id"))
spark.range(1).withColumnRenamed("id", "x").sort($"id")
spark.range(1).withColumnRenamed("id", "x").sort('id)

This sort API should defer attribute resolution to analysis.

How was this patch tested?

Added unit test.

@viirya, it looks something is wrong with JIRA and somewhere executing dev/github_jira_sync.py. It looks #18740 was already submitted

@HyukjinKwon oh. I see. Thanks.
