programatic error in Product : Controller : Updatecart while in 'catalogue' mode

-- HikaShop version -- : 3.3
-- Joomla version -- : 3.8.5

We are using a wishlist in catalogue mode. The feature of adding items to the wishlist worked in 3.2.2 but stopped in 3.3. I was able to trace it to /components/com_hikashop/controllers/product.php, funtion updatecart(), starting around line 332 - the condition if($config->get('catalogue')). The next line calls variable $tmpl which has not been defined at that point. This appears to be a leftover code snippet from 3.2.2. If I do define $tmpl according to the code in 3.2.2, this condition returns false and an item is not added.

I'm not sure what processing was intended for this 'catalogue' condition, but I was able to get our functionality back by commenting out the entire condition.

When you have a fix ready - even if it is just a snippet of code for me to drop in -- please let us know. I seem to have it working for now, but I would prefer to update to the intended code instead of waiting until 3.3.1.
