Fix exception on translation of objects

Sometimes, the content of translations[module.name][key] is not a string but an entire object. It cause a crash on template.replace(...) of createStringFromTemplate(...). It is currently the case of MMM-Voice-Control and the previous commit have broked this module (10 month ago... I am surprised to be the first founded it)
