Additional welcome URL is shown in ESR 45 based Tor Browser

Testing a build with tor-browser-45.0.2esr-6.x-1 resulted in startup.homepage_welcome_url.additional's value being loaded on first start for some reason. Maybe we have forgotten to bump a pref here? Skimming our pref file did not show something obvious here, though.

This is due to

additionalPage = Services.urlFormatter.formatURLPref("startup.homepage_welcome_url.additional");


    if (additionalPage && additionalPage != "about:blank") {
      if (overridePage) {
        overridePage += "|" + additionalPage;
      } else {
        overridePage = additionalPage;

In Tor Browser based on ESR38 overridePage is an empty string.
