[BUGFIX beta] Remove Namespace processing
[BUGFIX beta] Remove Namespace processing

Ember no longer uses Namespaces in the `toString` on classes, so there's
no reason to eagerly process namespaces on application boot. This is
currently triggering the deprecation message in new Ember applications
on Beta, so this removes it to prevent that.
