Explicitly register the model classes (see #1951)

Description
-----------

I have realized that using `Model::getRelated()` still relies on the old Contao 3 class autoloader to find the related model class. This is because `Model::getClassFromTable()` only converts `tl_page` to `PageModel` and not to `Contao\PageModel` and therefore we still have "composerized" classes in Contao 4.10 when we really should not anymore. 😄

This PR explicitly registers the fully qualified model class names.
