Change subject: Gracefully handle invalid links when handling redlinks
......................................................................
Gracefully handle invalid links when handling redlinks
There is no guarantee just because a link was created by parsoid that it will
resolve to a valid Title object. If the link doesn't resolve to a valid title
then just ignore it.
