Remove from language files lines that don't have the correct number of %s parameters

See existing test in LanguagesManager.
The test could simply be extended to overwrite translation files, and remove these strings that don't match properly.
Old files could be saved as $code.backup.php
This would fix many small issues for Piwik users (link that doesn't display properly because the translator forgot one %s)
