Fix relative URL path handling with clone_url
!3518 (merged)
refactored GetRemoteURL() but inadvertently caused relative paths to
be dropped when clone_url is configured. This makes clones fail
since the constructed clone URL will return a 404.
This commit restores the previous behavior of appending the project
path to the specified clone_url path.
Relates to #29522 (closed)
