Filter Count Gadget only works if the instance have Service Desk Application

Update:

Hey everyone, a bit of an update on this ticket - this gadget was intended to work for JSD only, and the best way we chose going forward to prevent non-JSD instances from running into an gadget that can't work for them, is to prevent that gadget from being visible from non-JSD instances. Supporting it for non-JSD instances is something we've looked into and is far more complex to make happen. Please go to this suggestion ticket and vote on it if you'd like to see this happen.
