Settings WebUI: Fix extensions url on cleanup result page

The cleaner success string now has HTML in it, and the JS i18n
function strips it off. i18nAdvanced allows us to let the <a> through to
the string, but the way the cleanup result page works is it simply sets
the card text variable ("title") to the result message string. This
would result in the raw string (with HTML) getting displayed, so the
title variable needs to also be set to be the inner-h-t-m-l.
