System tags are designed not to appear in most UI - they are auto-added
by models so that they can be searched on and have other functionality.
A custom manager on the Tag prevents these appearing in e.g. admin for
users when tagging items. But other managers allow access to the whole
world of tags. Here we test these managers, as well as the rendering of
system tags.
