When project moved, original image references are broken

Summary

• The issue images are broken when the project is moved from one group to another group.
• In my particular case I moved it from group/sub-group/project to newGroup/project

Steps to reproduce

• Create a project in under any group/sub-group
• Create an issue and upload an image in the description
• Move the project to a newGroup
• Now the images in the issue is broken.

What is the current bug behavior?

I'm not sure if this bug exists for all moved projects or for my particular case.

• The image URL when I open it in the new tab does a 302 redirect to a wrong URL
• If the URL was https://mydomain.com/group/sub-group/project/uploads/<some-hash>/filename.png
• It does a 302 to https://mydomain.com/uploads/newGroup/project/<some-hash>/filename.png.html
• The /uploads came at the beginning of the path, and it ends with .html

What is the expected correct behavior?

• It should do a 302 to https://mydomain.com/newGroup/project/uploads/<some-hash>/filename.png
