$input->cookie->set() sets wrong expiry by default

[Toutouwai]

The docs for WireInputDataCookie::set() say that if the age option is omitted then the default is "0, expire with session".

But actually the expiry set to the cookie ends up being 1 week. This seems to be coming from $config->cookieOptions in /wire/config.php
