Add wikilinks fixing to content scrubber

[Chris Rossi]

This is the Phase 2 described in #381694.

In Karl2 wiki links were able to differ wildly from the page title they were link to, which in Karl3 broke a lot of wiki links, since we expect the link to match exactly the linked to page title.

As a quick fix, we have relaxed the matching algorithm used in karl.content.models.wiki:cook to allow the differences found in Karl2 to just work. Ultimately, though, we don't want to support the loose matching rules in Karl2. To this end we are going to update the content scrubber to alter any wikilinks which currently match loosely to match exactly their referenced page titles, and then revert the wiki page cooking logic to use exact matching again.

I'm going to mark this as Low, as it is somewhat optional. The purpose of this task is to allow us to remove the hack.

I chatted with Shane, and we agreed that we ought to get out of the idea of sticking all issues related to X to just one person. I explained that our goal to close this task is to clean up some content and remove a shim we had in place. He can get the details from Chris.

Note that Shane is also working in this neighborhood on https://bugs.launchpad.net/karl3/+bug/399353
