If there's parent processing handle, we don't need to create completely new report group and status report - we'll just reuse the one already initialized for the parent. Currently, the situation where this matter is when doing internal report to do the selection for processing commands where we have parent processing handle for the command itself and processing handle for the selection part (that is selection for non-reporting tools).
