[issue41478] Empty representation of AssertionError

Changing behavior and it's impact on existing code is, without a doubt, a
big deal here. Maybe it's a reason not to do anything about it.

Just to understand guiding design principle, what is expected from __str__
in more general case? I thought about it as "user-friendly string
representation", therefore expected an Exception without a message to
identify itself by it's class.
