Fixing issue with CookieJar not loading at boot.

* Using the "QTimer::singleShot" bites back in the ass
* The "script" takes priority and runs before the SLOT is actually invoked

Why was I using a Timer?
Not sure anymore: it must have slipped in while I was trying to work out
all the other issues I had with QNetworkCookieJar, and I left it there.
