Ignore a new pep8-naming error
The new error <https://github.com/PyCQA/pep8-naming/pull/157> strikes me
as a little overzealous: while most exceptions are errors, there are
some Exception subclasses that are *not* properly considered errors
(e.g., when they're only a base class for other error classes).
