Title: BUG: URL-segment validation incorrect when Translatable is used

URL-segment validation is incorrect when the Translatable module is used.
In this case it fails to find pages in other locales with the same URL-
segment.

Fixed by disabling Translatable's locale-filter before searching for
pages with an identical URL-segment (after checking if the Translatable-
class is present).
