[issue21728] Confusing error message when initialising type inheriting object.__init__

[Gerrit Holl]

New submission from Gerrit Holl:

When I initialise a class that doesn't define its own __init__, but I still pass arguments, the error message is confusing:

>>> class A: pass
... 
>>> A(42)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: object() takes no parameters

Although it is correct that object() takes no parameters, it would be more correct to state that A() does not take any parameters.
