Closes #52703

See merge request gitlab-org/gitlab-ce!29937

Checks that archives of two different user projects with the same name aren't the same via checksum.  I.E. a user can't download the archive of another's project by mistake.

Use absolute paths for SCSS imports

I forgot to clean up this bit in we switched the `forked_from_project`
relation to use fork networks in
https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/22226

Also:
- stub MutationObserver in Jest

A recent update in [GitLab UI] and setting the [config.assets.paths] to
include `node_modules` for the resolution of SCSS imports, allows us to
have much nicer imports which don't rely on brittle relative paths.

This change also forwards @gitlab/ui to the newest version
