Update the categories (remove) warnings

-- HikaShop version -- : 4.4.1
-- Joomla version -- : 3.9.24
-- PHP version -- : 7.3.27

I get this warnings on Mass Actions when I was trying to remove the "product category" from products.
The job was done anyway.

Hello,

Thank you for your feedback !
Note that the "product category" category is used by Hikashop's system, so if you have any problem with your categories, you can always rebuild your product category tree through your category listing page : "Hikashop->Products->Categories".

Kind regards,
Mohamed.
