Use nntp-open-tls-stream in url-snews

[Diane Murray <disumu@x3y2z1.net>]

url-snews still uses `nntp-open-ssl-stream' as the default function to
open connections unless the `url-gateway-method' is set to tls.  This
patch changes it to use `nntp-open-tls-stream'.  This also fixes a bug
where an error would occur because the function names weren't quoted.

	* url-news.el (url-snews): Always use `nntp-open-tls-stream'.
