PLANET-5605 Always add apps login filter

* This filter is needed to prevent the cookie from being set anywhere
but the login page. If you don't add the filter then the cookie is
always set.
* The checks were in place to prevent other things from setting cookies.
Those things are not there anymore, so we don't need the checks.
