Cookie not set with SameSite attribute

As noted on solid-auth-client https://github.com/solid/solid-auth-client/issues/151, Chrome is requiring third party cookies to be set with SameSite=None and Secure. While this setting is not yet active on desktop, it is active on Android and therefore breaks all Solid apps using the nssidp.sid cookie from .solid.community.
This can still be bypassed by disabling chrome://flags/#same-site-by-default-cookies.
Presumably non-cookie based authentication doesn't have this issue but I'm not sure it's possible to turn off cookie-based authentication at the moment (https://github.com/solid/node-solid-server/issues/672)

I'm not an expert, but it appears the change required is in the definition of the express-session settings
https://github.com/solid/node-solid-server/blob/master/lib/create-app.js#L305
https://www.npmjs.com/package/express-session#cookiesamesite

It may be sufficient to simply use:

    cookie: {
      maxAge: 24 * 60 * 60 * 1000,
      sameSite:'None'
    }

It seems that http connections should also be completely dropped for authenticated sessions because the third party cookie won't be sent without cookie.secure=true anyway.

从 lib/create-app.js 中大约第 305 行开始，结合 express-session 文档检查 express-session 的 Cookie 设置。在启用 SameSite Cookie 强制执行的情况下，在 Android Chrome 中复现 nssidp.sid 的行为，然后验证经过身份验证的 Solid 应用能够建立并使用会话，同时不会破坏受支持的连接模式。
