Fix CLI test expectation for nonexistent command execution

- TestErrorHandling should not expect error for nonexistent commands
- The jail starts successfully, only the command inside fails (correct behavior)
- Command execution failure is logged but doesn't cause Run() to return error
- This aligns with expected behavior where jail infrastructure works properly
