When trying to view the Repository Admin page, the master branch throws a "Object is not serializable" error because the value getting passed is a Promise (django.utils.functional.Promise) object rather than a decodable string. Create a LazyEncoder that will check for this type and call force_text on it so that it gets initialized properly.

WebUI - Ensured that the repository admin page works fine.
