Enforce the selection of a landing page for WoltLab Suite Core in applicationManagement

This is enforced in the template only, because the PHP logic already needs to
handle a NULL landing page, as the global landing page could be deleted or
uninstalled. It will implicitly fall back to the ArticleList then.

Resolves #4843
