Scenario:

• User want to generate attribution for https://commons.wikimedia.org/wiki/File:!!!_new_moon_!!!.jpg (CC-BY-2.0)
• User chooses "I want to use an edited version of the image"
• User chooses a different license the image should be published under (e.g. CC-BY-3.0)
• Current behavior: Attribution just contains the new license (CC-BY-3.0)
• Desired behavior: Attribution should contain the new license AND a reference to the licence of the original image.
• Optional: this only applies to images that have a license < CC-BY-4.0

Estimation:

• Always include original license in the attribution
• Include original license in the attribution for images with a license < CC-BY-4.0

Currently, in the generated attribution, only the new license is shown
