We found that field changes, close notes comments are copied twice to activity stream when we close a case. This issue is observed in Kingston as well

1. Open any existing open case. Enter close notes and click on close case.
2. Check the activity stream and observe that state changes, close notes are copied twice.
   
   Refer the screenshot attached.

Please update the business rule: "Close escalation" (sys_script_9097abeeb3500300ff6e6e5f26a8dcb1.xml ) in the following way:

- Set When field to 'before' (this is currently set to after).

- Remove the redundant update call line 15. This can be commented out or deleted.
