    Remove context also for translated strings
    
    This is consistent with the treatment in LyX itself (cleanTranslation() is
    also called on the translated strings), and some translators leave the 
context
    in the translated msgstr (e.g. [[List of Listings]]), although that is not
    recommended. Without this, lib/layouttranslations would contain wrong
    translations.
