IMPALA-8772: Import Testcase failed for SQL without table refs
Description:
Query like this: select 5 * 4; can generate valid testcase, but
cannot be loaded because it does not involve any table and view
references.
Fix:
Add null check for CatalogOpExecutor when doing testcase data load
Tests:
tests/metadata/test_testcase_builder
Change-Id: I50d77d7de44bb140598a1e8db4da85a5ec87f31e
TODO: NEED TO DELETE GENERATED TESTCASE AFTER THIS IS DONE
