Remove redundant 301 redirect headers before 404 in editor include

[uldisrudzitis]

The 301 status/Location headers were always overwritten by the subsequent include of error/404.php, which sets its own 404 status. The Location header was left dangling on the final 404 response with no effect, since browsers only act on it for 3xx/201 responses.
