Fix URL used for refreshing notes if relative_url is present
What does this MR do?
This MR fixes URLs used for refreshing notes - the relative_url prefix was appended twice
Are there points in the code the reviewer needs to double check?
No
Why was this MR needed?
In case of relative_url installation, opening a page which does refresh notes (i.e. merge request), the page generates lots of 404 errors in the browser console. It turns out that the relative_url is prepended to the link twice.
