Why do you need this?

This friend declaration existed because
UserManagerTest::ResetUserManagerLoggedInUser() was calling the private
User::~User(). It is no longer necessary as the destructor is called from
UserManager::LogoutForTest() now.

 
   // Do not allow anyone else to create new User instances.
   User(const std::string& email, bool is_guest);
   ~User();
 
   // Setters are private so only UserManager can call them.
   void SetImage(const SkBitmap& image, int image_index);
   // Sets a stub image until the next |SetImage| call. |image_index| may be
   // one of |kExternalImageIndex| or |kProfileImageIndex|.
