Mms: No delivery check-mark if both delivery and read report enabled

If read report enabled, it always displays "detail" icon on UI, no
matter what if delivery report or read report enabled.

Change the check-mark avaiable only for delivery report.
If only "read report" enabled, just show "detail" icon instead.
