[BUGFIX] Use _LOCALIZED_UID also for pages in Extbase persistence

When pages use overlays, the special key "_PAGES_OVERLAY_UID"
is used (PageRepository->getPageOverlay), for other
pages doing overlays, the property "_LOCALIZED_UID" is used
(PageRepository->getRecordOverlay).

Extbase is setting the special property $_localizedUid in
a Domain Model, based on the key "_LOCALIZED_UID" in the
DataMapper. The Typo3DbBackend now maps the _PAGES_OVERLAY_UID
onto the _LOCALIZED_UID in order to have Extbase deal with
language overlays in pages as well.
