Actually... looking back on Kal's original comment... I'd like to hear some
steps on how to reproduce this problem.

Because currently Koha will generate an empty "normalized_isbn" value for a
ISBN starting with 979, so Koha shouldn't be trying to display any cover
images. I just tested in koha-testing-docker and no cover image is even
attempted with a record with the 9798885795692 ISBN. So... I'm not sure how
this could be happening in Koha. 

Now I think that we should upgrade Business::ISBN because we do want to support
ISBNs starting with 979. I think that will be a bit of work.

However, even if we do that, Amazon is still going to be a problem. From past
experience, I don't think that Amazon actually supports ISBN-13 at all when it
comes to cover images.

For example, note that all 3 of these URLs returns the same image.

In the past, I think that's why we've used the ISBN-10 version for requesting
images from Amazon. 

ISBN-13 with 979 is going to be a problem for Amazon images in particular.
