Fix XSS vulnerability in channel playlists
The channel/<ucid>/playlists page was vulnerable to Cross Site Scripting
(XSS), because the different URL parameters were inserted as-is in the URL
meant for instance switching.

This vulnerability could allow an attacker to inject malicious Javascript
in the page by tricking the user to click on a crafted link.

Bug introduced in commit 66e7285108363c3c3dcb814bdffb716c14e1724d
("Only use /redirect when automatically redirecting").

Thanks to Jack (@testa:cthd.icu on Matrix, @cysea on github) for responsibly
reporting this issue!
