If this is a regression, please provide more details to justify this:


Steps to Reproduce:
1. Configure 3 OCP 4.13 clusters. hub/acm, c1 and c2. 
2. Configure MDR
3. Deploy Appset based apps on c1. 
4. Delete an appset application with "Remove ApplicationSet related resources" box checked. (screenshot)


Actual results:
Application is deleted in c1 but the 'placement' resource of the app persists on hub.

Expected results:
If "Remove ApplicationSet related resources" is selected while deleting, the application and all its resources must be deleted

Additional info:

If the app placement is not deleted manually, there will be an error while creating new appset based app with same name. Like: <app-name>-placement already exists.
