Fixed issue with backup delete

1) Updated class level create_backup function to wait for resource delete
2) Switched the wait_for_resource_deletion handler before delete_backup,
   the clean_up function uses list pop() to perform cleanup. The backup
   has to be deleted before the wait_handler is called
