get_user_teams the case of being a member of zero teams

I'm wondering if get_user_teams of class User should **not** throw an exception on an empty list as below.
```
if api_call == list() or api_call[0].get("id") is None:
                logging.error(f"Check the error: {api_call}.")
                raise Exception 
```
A user being a member of zero teams seems like a valid outcome to me?
