Add group name to GroupStateTriggerHandler (#3536) 

* Add group name to GroupStateTriggerHandler

When triggering on state change/update of group member, the group is not available in the rule context (because the event is the `ItemStateChanged/UpdatedEvent` that caused the group to change/update. This adds a new element `triggeringGroup` to the rule context.

This is useful for generalized rules that trigger on different groups.
