[devtools/testlib] Port CubicWebTC.view() to py3k
testlib.TestCase.set_description's argument will eventually be printed
out to sys.stdout/stderr. On python 2, this object takes bytes-like
objects (eg, str) whereas python 3's takes unicode-like objects and
handles the encoding on its own.
Thus the 'str' type can used in both versions to eventually display the
description on screen.
