Merge ~cjwatson/launchpad:remove-zope.testing.renormalizing into launchpad:master

[Colin Watson]

Remove most uses of zope.testing.renormalizing

We were mainly using this module for the `IGNORE_EXCEPTION_MODULE_IN_PYTHON2` option flag, but we no longer need that. `lp.services.mail.tests.test_stub` still has a legitimate use for this module, since it does regex substitution on the output of one example.

[Cristian Gonzalez (cristiangsp)]

Looks good!
