Test suite: workaround occasionally disabled JavaScript when testing releases as well
We already workaround this bug for non-releases, when the original startup page title is "Tails - Trying a testing version of Tails", and the lack of JavaScript never replaces it with the correct "Tails". Let's also workaround it when testing releases, when the original startup page is "Tails - Welcome to Tails!"
