Pattern: __getnewargs__ does not return tuple

Issue: -

Description

Used when a __getnewargs__ method returns something which is not a tuple.

Example of incorrect code:

class BadGetNewArgs(object):
    """ __getnewargs__ returns an integer """

    def __getnewargs__(self):  # [invalid-getnewargs-returned]
        return 1

Example of correct code:

class GoodGetNewArgs(object):
    """__getnewargs__ returns <type 'tuple'>"""

    def __getnewargs__(self):
        return (1, "2", 3)
