Title: Make unit tests compatible with Python 2.6

So far, while musicbrainzngs itself was compatible with Python 2.6, the
unit tests were written using features of unittest introduced by Python
2.7. This patch replaces unittest by unittest2 if the version of Python
is older than 2.7

I wrote this patch as part of my packaging work for Debian.
