Fix issue where requestAction() would not strip base url.

requestAction + Controller::referer() don't work well together.
Stripping the base domain, and normalizing the URL gives an application
request which works much better.  This keeps RequestHandler more
transparent when overloading redirects.

Fixes #2711
