It isn't very intuitive that this link points to the stats page, but
since it's the only page linking to it and there's no link pointing to
it in the admin navigation, I guess it's better than offering no clue at
all of the current whereabouts.
We were repeating the same code over and over (with a few variants) to
setup tests which require an administrator. We can use a tag and
simplify the code.
