Travis: Initiating build for commit 'dc0544c12767ca6f2d1679c87c3e94f0bc9982ff' on branch '5863_languageFilesInPlugin': refs #5863 we need to pass the langCode to loadPluginTranslations() otherwise langCode will be always an empty string. If there is no plugin loaded yet and no language generate a simple cache file for core translations, load a translation only if a langCode is there
