[TASK] Check for l10n overlays move only when necessary

When moving a sys_language_uid=0 record, existing localization
overlay records are usually moved as well. The patch optimizes
the code to not check for localization overlays if the moved
record is a localized record already. This can save another few
DB calls in DataHandler.
