[SPARK-19775][SQL] Remove an obsolete partitionBy().insertInto() test case

## What changes were proposed in this pull request?

This issue removes [a test case](https://github.com/apache/spark/blame/master/sql/hive/src/test/scala/org/apache/spark/sql/hive/InsertIntoHiveTableSuite.scala#L287-L298) which was introduced by [SPARK-14459](652bbb1) and was superseded by [SPARK-16033](https://github.com/apache/spark/blame/master/sql/hive/src/test/scala/org/apache/spark/sql/hive/InsertIntoHiveTableSuite.scala#L365-L371). Basically, we cannot use `partitionBy` and `insertInto` together.

```scala
  test("Reject partitioning that does not match table") {
    withSQLConf(("hive.exec.dynamic.partition.mode", "nonstrict")) {
      sql("CREATE TABLE partitioned (id bigint, data string) PARTITIONED BY (part string)")
      val data = (1 to 10).map(i => (i, s"data-$i", if ((i % 2) == 0) "even" else "odd"))
          .toDF("id", "data", "part")

      intercept[AnalysisException] {
        // cannot partition by 2 fields when there is only one in the table definition
        data.write.partitionBy("part", "data").insertInto("partitioned")
      }
    }
  }
```

## How was this patch tested?

This only removes a test case. Pass the existing Jenkins test.
