Fix unit tests

After migrating to java 17 and changing some files in the project, some unit tests broke.

• ResourceOrderIntegrationTest -> testResourceOrderCreate

• ResourcePoolIntegrationTest -> testResourcePoolCreateAndUpdate

• ResourceInventoryIntegrationTest -> testResourceCreateAndUpdate

• ServiceCatalogIntegrationTest -> testCloneSpec, testSpecAttributesUpdate

• ResourceCatalogIntegrationTest -> addCatalogAddCategory, manageCategoriesSubCategories, _countDefaultProperties, testSpecAttributesUpdate, testBundledSpec, testSpecAttachment, testLogicalPhysicalResources
