Remove outdated AppInfo string after main translations for updated string arrived

[wutschel]

Remove "Official Kodi Remote app uses artwork downloaded from your Kodi server or from the internet when your Kodi server refers to it. To unleash the beauty of artwork use Kodi's "Universal Scraper" or other scraper add-ons.\n\nKodi logo, Zappy mascot and Official Kodi Remote icons are property of Kodi Foundation.\nhttp://www.kodi.tv/contribute\n\n - Team Kodi" from EN language file. This was only kept to make the translation update easier as in the updated string only ", Zappy mascot" has been removed.
