[BUGFIX] Check default language for preview requirements

When previewing a translated page that is enabled which has
a parent (default lang) page that is hidden, users got a 403
error, because the preview flag was not set (as the page itself
was not hidden).

Change the check to always check both the default language and
the overlay for setting the preview flag.
