test-requirements.txt is pulling django 1.6 and braking unittests

[Yves-Gwenael Bourhis]

"pip install -Ur test-requirements.txt" pulls django-nose, and django-nose pulls django 1.6 even though we have "Django>=1.4,<1.6" in test-requirements.txt:

Downloading/unpacking Django>=1.2 from https://pypi.python.org/packages/source/D/Django/Django-1.6.tar.gz#md5=65db1bc313124c3754c89073942e38a8 (from django-nose->-r test-requirements.txt (line 5))

runing "./run_tests.sh" in a new environment pulls test-requirements.txt and unittests fail in .venv/local/lib/python2.7/site-packages/openstack_auth/urls.py", line 14 "from django.conf.urls.defaults import patterns, url" : ImportError: No module named defaults

runing "pip install -Ur requirements.txt" after "pip install -Ur test-requirements.txt" (and before launching ./run_tests.sh) fixes the issue by downgrading the django version.
