[SPARK-23275][SQL] fix the thread leaking in hive/tests
## What changes were proposed in this pull request?
The two lines actually can trigger the hive metastore bug:
https://issues.apache.org/jira/browse/HIVE-16844
The two configs are not in the default `ObjectStore` properties, so any run
hive commands after these two lines will set the `propsChanged` flag in the
`ObjectStore.setConf` and then cause thread leaks.
I don't think two lines are very useful and can be removed completed.
## How was this patch tested?
(Please explain how this patch was tested. E.g. unit tests, integration
tests, manual tests)
(If this patch involves UI changes, please attach a screenshot; otherwise,
remove this)
