[ticket/11352] Redirection not happening after disapproving a post.

When moderator is viewing a disapproved topic and clicking
on disapprove button, a confirm box will popup. After confirming
disapproval, screen will still remain in quick reply view
where quick reply should not exist for a disapproved topic.
Desired behavior is to redirecting it to forum page. Enabled
ajax-refresh in topic approve form. Changed redirection url
to forum page in mcp_queue.php.
