IMPALA-12526: Fix NullPointerException in testResetMetadataDesc
BackendConfig.INSTANCE could be null when running
CatalogOpUtilTest#testResetMetadataDesc(). This patch adds a setup
method to make sure it's initialized.
Tests
- Verified the issue is resolved by running the test individually:
(pushd fe && mvn test -Dtest=CatalogOpUtilTest#testResetMetadataDesc)
