Add test for retrieving calendar group by name with verbose output

- Implemented a new test case to verify the retrieval of a calendar group by name for the signed-in user when verbose output is enabled.
- Enhanced logging assertions to ensure correct output during the command execution.
- Stubbed API request to simulate expected behavior for the test scenario.
