Broken REST API to get member from list given email address (and role).

There is code in src/mailman/rest/lists.py to allow for the REST API to return a member object given a list, role and email address, but it is currently broken.

the last line of the member function in lists.py:

        return AMember(self._mlist, role, address)

compare to AMember constructor:

        def __init__(self, member_id):

Attempting to use this part of the API returns a 500 with this traceback:
