cc @srowen , this pr fix all failed test cases in sql/hive module.

In this patch add test-2.13.jar to sql/hive/src/test/resources/regression-test-SPARK-8489 dir, the test-2.13.jar not a copy of test-2.12.jar, I try to generate test-2.13 as #22308 but failed because there is no spark 3.1.0-SNAPSHOT deploy in maven repository, and I generate it as follow:

1. create a test module in spark source
2. copy Main.scala and MyCoolClass.scala to src/main/scala dir of test module
3. create a pom.xml use spark base pom.xml as parent pom and add dependency

    <dependency>
      <groupId>org.apache.spark</groupId>
      <artifactId>spark-sql_${scala.binary.version}</artifactId>
      <version>${project.version}</version>
    </dependency>

4. mvn build test module with -am and rename original-test-2.13-3.1.0-SNAPSHOT.jar to test-2.13.jar

Can we just check isEmpty?
