The QUnit tests for user saving are currently failing with somewhat strange behavior:

* Save REST operation is executed without any error thrown.
* Subsequent test to load user with the ID returned fails, causing test to fail.
* If you go to another page, or reload the tests, the Drupal message displayed on the next page says the user has been created, and gives a link.
* If you click on that link, you get a page not found, and the user is not in the list of users in the People admin page.

I'm pretty stumped on this one, but suspect it's something either on the Services side or in the way Backbone is using services. Perhaps there's a flag we need to set or something?
