import_export: use proper links in MR and issues activity notes
I imported the project https://gitlab.com/victornoel/petals-cockpit (8.15.2-ee) into a docker instance of gitlab 8.15.2-ce. I did it as an admin.
You can see the link point to the original project URL (bottom of the window) and not the new one (address bar of the browser).
It would be great if this could be improved… not sure how :)
