Samsite session cookie breaks twitter integration
```
app.use(session({
      secret: 'foo',
      name: 'bar',
      cookie: {
        httpOnly: true,
        path: '/',
        secure: true,
        signed: true,
        sameSite: true
      },
      saveUninitialized: false,
      resave: false
    }))
```

yields this for twitter: **Grant: missing session or misconfigured provider**

Any specific reason?
