Done.

just move this DCHECK() to GetDesktopBrowser()

can you do something long the lines of:

  CloseModalSignInWindow(browser,
                         LoginUIService::SYNC_WITH_DEFAULT_SETTINGS);

where

  void CloseModalSignInWindow(Browser* browser, ...) {
    LoginUIServiceFactory::GetForProfile(browser->profile())->
        SyncConfirmationUIClosed(...);
    browser->window()->CloseModalSignInWindow();
  }
