Unlock Results image aspect ratio

Description: **VALUE STATEMENT:**
When an assessment author builds an assessment, they may choose an optional image to show as part of the result. As a user, I should be able to see the author’s image in the correct aspect ratio.

– Simple Result
– The author can upload an image and IS NOT force to crop the image. Therefore, the full uncropped image should be shown.
– The image should fill the result image container and NOT be narrower than the module.
