    Fix a lack of method arguments at tempauth

    This fixes a kind of trivial issue with TypeError caused by a lack
    of method argument at calling.

    When using 'Authorization' header with tempauth, tempauth calls
    _get_user_groups with 3 arguments (includes self) on current code
    but the method requires 4 arguments so it will go to fail with 500.

    This patch fixes to take correct arguments and adds an unit test
    for the case.
