[sdi/header] Application list is rendered even if no user is logged
The application list in the header-toolbar is rendered with links to the atlas, studio, alias and metadata apps even if there is no logged user.
This is a problem because when there is no logged user, we give access to the studio, the alias and metadata apps, and it shouldn't be.
We can see the problem on https://safe-brussels.champs-libres.be/client/view/.
Be careful, because the problem is not there on https://geodata.environnement.brussels/client/view/, where the app list is actually useful to have access to the solar, brugeotool, etc. apps.
This has to be changed in https://gitlab.com/atelier-cartographique/carto-station/-/blame/master/clients/sdi/components/header.ts#L137
