Fix notifications not showing up/being reset

What does this MR do and why?

Fix notifications being reset when we fail to reach craftycontrol.com The proposed solution is to catch the request exception and return falsey. When we get a falsey response from getAnnoucements we will return a 424 dependency error with a description that we could not get notifications from craftycontrol.com
