Issue 23471 - fix call to xtcommission.getsalesreps()

This function's call to xtcommission.getsalesreps() was not updated to include the two new parameters, saletype_id and item_custprice, thereby leading to the SQL error noted in the issue.  While this function was not explicitly included in the issue, the same issue that caused the error noted in the issue in the convert quote to SO process was also found in this function that converts a quote to an invoice.
