fix: Root users incorrectly getting warning they have no rights (#1368)

* Don't show root users the no-content warning

When logged in as a root user (who has no content)
and on the home dashboard page
then don't show the no content nag box

Also: users who are editors have content even if they have no tags,
neighbourhoods or partners. Like root users.
