This change is in conflict with some code we added at the top to attempt to solve this same problem. See: https://github.com/racker/cookbook-cloudmonitoring/blob/master/providers/alarm.rb#L7 (same as for the check provider).

I think the way we fixed it is more comprehensive, because it clears the broken view as well that is caused by having a nil entity -- but it's also more expensive on the API side (we do more overview calls).
