Subject: [PATCH] Backport PR #6117: Remove / from route of TreeRedirectHandler.

When base_url is set, navigating to http://{url}/{base_url} returns 404

This is due to the TreeRedirectHandler only picking up http://{url}/{base_url}/ and the TrailingSlashHandler being set to {base_url}/.*/.

This change will cause http://{url}/{base_url} to correctly redirect to http://{url}/{base_url}/tree, as expected.
