    util: Filter out message context of untranslated strings
    
    Commit 5a47ad837b changed the definition of NC_() to include the
    message context, so that gettext can correctly disambiguate strings
    like "S". However this does only work when gettext actually returns
    a translation from the catalogue; if the string is not found, we
    need to strip the context again to not have it show up in the UI.
