  - GER-952 : Delete-project plugin : 500 server error when clicking on delete for a project
    
    This jira was reopened as we did not process the delete request correctly whenever the database was NoteDB. The database handler for the delete-project plugin has now been updated to handle NoteDB as well as ReviewDB changes.
