(bug 43701) - LinkedPage was linked by 127.0.0.1 from page

If multiple pages are transcluding a page, a link update on the page being transcluded would trigger notifications for all the transcluding pages, we only need to fire the notification for the page being transcluded.

The solution in this patch seems to work but I have not fully investigated all possible scenarios. -2 for now
