Broken legacy forum link redirection

http://minetest.net/forum/viewtopic.php?id=4345 (link found in the glooptest mod) redirects to
https://forum.luanti.org/viewtopic.php?id=4345 (not found), whereas
https://forum.luanti.org/viewtopic.php?t=4345 shows the correct post.

Maybe relevant code: (didn't test)
