[BUGFIX] Tests for translated content will prepare a translated page

Language handling always bases on the existence of a page version for
the requested language. If this is not available, handling follows
fallback settings.

Functional Tests that test for translated content to be returned
as expected must provide such a translated page on their own, else
the fallback handling kicks in, renders the test falsly reassuring.
