This code is temporary. However, please add a comment discussing what you are
doing.
For instance, it does matter that OnManagedUserInitialized() will always occur
after NOTIFICATION_EXTENSIONS_READY notification.
The initialization of the ManagedUserService is not really interesting per se,
we really care that ProfileManager::InitProfileUserPrefs() has run.
The point is, this code is pretty subtle and worth a comment.

Done.
