Only update the payment intent if the total price has changed

vmarchuk → made their first commit to this issue’s fork.

I've also updated the code to enqueue items only if we really need to update the PaymentIntent.

Updated MR to compare $order->getTotalPrice() with $order->original->getTotalPrice().

Looks good to me!

Assigning credit.

We still need to fix the failed tests.

Thanks tests I found the problem. There are cases where $total_price and $original_price may not exist, for example, a product has been added to an empty cart (so $original_price doesn't exist) or the last product has been removed from the cart (so $total_price doesn't exist).
See the new method I added getChangedOrderTotalPrice() with comments, it seems to cover all cases.
