Since, for whatever reason, the qa env did run with Python 3 for me I didn't
spotted those: '\u1234' is the same as '\\u1234' since \u has no meaning in
non-unicode strings, hence the backslash is just interpreted as backslash and
the literal doesn't match repr() anymore. So this isn't only against our coding
style, but also rendered this test useless on Python 2. ;)

[Sebastian Noack, 2016/05/27 12:54:55]

I reverted changes of patch set 2. My conclusion above is wrong, as this file
uses "from __future__ import unicode_literals" which flake8-abp is going to
account for with issue 4404.
