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.

Beginne in lib/create-app.js etwa bei Zeile 305 und überprüfe die Cookie-Einstellungen von express-session zusammen mit der Dokumentation zu express-session. Reproduziere das Verhalten von nssidp.sid in Android Chrome bei der Durchsetzung von SameSite-Cookies und überprüfe anschließend, dass authentifizierte Solid-Apps die Sitzung aufbauen und verwenden können, ohne die unterstützten Verbindungsmodi zu beeinträchtigen.
