Fix menu for 'disable extension'.

Fix menu for 'disable extension'.

- The 'display_source' field should specify the extension's name.
  It seems to be the field for such purpose (see DisplayNameForOrigin()
  method in DesktopNotificationService for example)
- Fix the strings of 'disable extension' menu item to show the
  extension's name.
- Fix the behavior of 'DisableExtension' in MessageCenterNotificationManager.
  It should not disable the extension itself, rather disable the notification
  ability for the extension.
