There are 2 separate unittests named "DurableCatalogTest"
(1) kv_engine_test_harness.cpp class DurableCatalogTest : public ServiceContextTest
(2) durable_catalog_test.cpp class DurableCatalogTest : public CatalogTestFixture

It's confusing to have 2 separate unittests with the same name - each set of tests should target specific features. We should clarify and adjust naming to better represent what each test class covers.
