Fix str(Unauthorized)
which is really problematic on python 3 where __unicode__ is never called
anymore. This was caused because in PY3, CubicWebException.__str__ was referencing
__unicode__ implementation of CubicWebException, not of its subclass that
implements it.
Fix a flake8 style warning about lambda assignment as a bonus.
