[BUGFIX] allowLanguageSynchronization flaws with pages_language_overlay

The allowLanguageSynchronization does not work correctly with the tables
pages and pages_language_overlay. This change at least provides the basic
functionality for regular non-relational values (which might work, but are
not verified with tests properly).
