Ensure constant order when setting all image tags

The newer version of tox (>=1.7.0) sets a random hash seed, which makes the
order of sets unpredictable. This patchset fixes the test_image_tag_set_all
test, which otherwise broke with a randomized PYTHONHASHSEED. This new tox
behaviour is consistent with python (>=3.3), meaning this change should avoid
bugs on that platform at a later date.
