Creating Duplicate Copies products_ordered

[todoonada]

When creating a duplicate of a product, the new copy of the products also inherits the number of products ordered from the original product.
I find this not desirable.

Let's say I have a product T-Shirt green and this was sold 100 times.
Later on there is a T-Shirt red available. It got all the same features like T-Shirt green, just a different color.
So I duplicate T-Shirt green and just change "green" to "red". This T-Shirt is also has products_ordered=100 in table products. It should be 0.

Maybe my understanding of the duplicate product function is wrong, but that is how I use it.
