when calling lists_membership on a member of class user, the wrong user is queried

[brett-schneider]

after querying people i follow (frens = api.friends), i wanted to find out in which list i or others keep them (frens[0].lists_membership()). from my understanding, frens[0].lists_membership() should return a list of lists that fren[0] is a member of. however i'm getting a list of lists that auth_user is a member of. i looked in model.py, which looks fine. could there be an issue with the unwrapping of resultset?

this looks suspicious:
user=self.screen_name
at models.py line 199

To clarify, this occurs because User.lists_membership passes the screen_name as user to API.lists_membership:

tweepy/tweepy/models.py

Line 199 in 9146c2e

return self._api.lists_memberships(user=self.screen_name,

which is not an allowed parameter, so the GET lists/memberships endpoint defaults to the memberships for the authenticating user instead.
