Fix/user deletion (#1157)

Extend the deleted user info with the username
- Because initially, we did not store the user name in the activity db 
Sometimes, we can not provide the user name in the API response.

Fix service user deletion
  - In case of service user deletion, do not invoke the IdP delete function
  - Prevent self deletion
