### Summary The group_rename system hook doesn't send the hook when a group is renamed. ### Steps to reproduce 1. Create a new system hook. 2. Create a new group. 3. Rename newly created group to something else. ### What is the current *bug* behavior? When the group is renamed there is no system hook sent according to 'Recent Deliveries' section of the system hook. ### What is the expected *correct* behavior? A POST request should be made to the specified URL in the system hook, and it should show in the Recent Deliveries.
