[SPARK-23000] [TEST] Keep Derby DB Location Unchanged After Session Cloning
## What changes were proposed in this pull request?
After session cloning in `TestHive`, the conf of the singleton SparkContext
for derby DB location is changed to a new directory. The directory is created
in `HiveUtils.newTemporaryConfiguration(useInMemoryDerby = false)`.
This PR is to keep the conf value of
`ConfVars.METASTORECONNECTURLKEY.varname` unchanged during the session clone.
## How was this patch tested?
The issue can be reproduced by the command:
> build/sbt -Phive "hive/test-only
org.apache.spark.sql.hive.HiveSessionStateSuite
org.apache.spark.sql.hive.DataSourceWithHiveMetastoreCatalogSuite"
Also added a test case.
