Deleting Order While Customer Is Viewing It Causes Double Display Of Orders Page

-- HikaShop version -- : 3.2.1
-- Joomla version -- : 3.8.2
-- PHP version -- : 7.1.11
-- Browser(s) name and version -- : Firefox 57.0

Perhaps a silly rare-case scenario, but:

1. If a customer is currently viewing an order (See shot1.jpg),
2. And the administrator happens to delete this order from the backend at this time,
3. If the customer now refreshes the page, the orders page will show but 2 times. Refreshing multiple times doesn't make a difference. See shot2.jpg.
4. Clicking on a different order and then clicking the Back button will show the correct layout. Using Back on browser will not.
