AssertionError in traitlets-5.2.2

[cgranade]

As of traitlets-5.2.2, packages that depend on traitlets (e.g.: the jupyter CLI tool) raise assertion errors when importing the traitlets package:

Traceback (most recent call last):

This is because the version in the package includes a .final appended so it doesn't match the string of the version number. Is this assertion check of the version being too clever by half?

EDIT: fix has already been PR'd: https://github.com/ipython/traitlets/pull/739/files
