Add error event to the firebase-query-behavior

It's a feature request. It would be grate to have error event when query can't be processed. For example when you try to read data from an URL but you don't have read access to it. The element will only remove an URL value from element's location attribute but will not tell you that it is something wrong. Event handling would be nice to have.
