[FIX] website_sale: add to cart (image too large)

Steps to reproduce:
1- enable "add to cart" feature on the website shop page
2- add any product to the cart
3- the image is way too large

Bug:
the animation creates a clone of the original image on which new css
classes has been added (h-100 w-100) that sets the image to full size

Fix:
since the CSS atribute of the new image are set in the function removing
all the classes of the original image solves the issue

Note:
the bug only started on 15.2 where the new classes have been added
merging on 15.0 just to prevent future issues
