Make the 'Group projects' links clickable in the admin screens

## What does this MR do?
This MR makes the group links within the 'users' section of the admin interface clickable. Currently, to view the details of groups a user is a member of, you have to go back to the 'groups' tab (which isn't ideal).

## Are there points in the code the reviewer needs to double check?
No

## Why was this MR needed?
It's a UX improvement - it saves going back to the 'groups' a user is a member of and then clicking the group to view the group details.

Fix typos

When a merge request can only be merged when all discussions are
resolved. This feature allows to easily delegate those discussions to a
new issue, while marking them as resolved in the merge request.

The user is presented with a new issue, prepared with mentions of all
unresolved discussions, including the first unresolved note of the
discussion, time and link to the note.

When the issue is created, the discussions in the merge request will get
a system note directing the user to the newly created issue.
