In #2445, I lifted out the fork button into its own template, but did
not update it properly. This resulted in the fork button's counter not
displaying, and pointing to the wrong place too.
This patch updates the template to account for it moving to a separate
file, and also adds test cases to verify the button is display as it
should be.
Fixes#2494.

For small, personal self-hosted instances with no user signups, the fork
button is just a noise. This patch allows disabling them like stars can
be disabled too.
Disabling forks does not only remove the buttons from the web UI, it
also disables the routes that could be used to create forks.
Fixes#2441.
