BUG Prioritise same-level pages in OldPageRedirector

Added option to pass integer ParentID=0 to OldPageRedirector::find_old_page to ensure search through nested pages from the root of SiteTree structure. Added new call of function and still offering fallback to old behaviour if first call returns false (fixed #2522)
