Tweaks to parserTests setup, redirect tests

* Disable editMode for parserTests as it now masks issues we see in
  production. This causes several new failures, mostly around quotes.
* Updated the blacklist to reflect these extra failures.
  TODO: Fix as many of those new failures in editMode.

* Add some Parsoid-only redirect tests
* Add colon escaping when serializing links to targets in the category and
  file namespaces
* Fix crasher on redirects to languages or interwikis
