Ensure that newly spawned task stack (dynamic) is getting freed up before test completion and thus preventing false memory leak indication failure. unit-test-app: add an API test_utils_task_delete This API ensures that dynamic memory of deleted task gets freed up before return. This helps for preventing false memory leak detections in test failures.
