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.

Reduce base font sizes across app by 1px

Looking at other websites that use system fonts, the default seems to be `14px`. We currently use `15px` which feels a little too big at the moment (in my opinion). This is just an idea so feel free to close it @awhildy 😄

Fix compatibility with Internet Explorer 11 for merge requests

## What does this MR do?
This merge request restores the compatibility with Internet Explorer 11.

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

## Why was this MR needed?
Commit ca3c0c6c introduced an incompatibility with Internet Explorer 11. On all merge requests in all projects the 'Changes' tab does not display the changes in IE11 but instead fails with 'Something went wrong on our end'. The reason ist, that this code snipped produces different results on Firefox and Internet Explorer 11:

```
var element = document.createElement('a');
element.href = '/some/absolute/url';
alert(element.pathname);
```

With Internet Explorer 11 the alert will print a relative path, whereas with Firefox the alert will print an absolute path. For GitLab this meant that a wrong AJAX URL was composed which resulted in a 404.

## Screenshots (if relevant)
None.
