BUG Lost session and some other vars in request

I have simple function defined in config/police.js

```js

module.exports.policies = {
'*': [
(req, res, next) => {
console.log('Session in police', req.session)
console.log(new Error().stack)
next()
},
],
}

```

And three test routes in config/routes.js

```js
'/': (req, res) => {
//req.session - exists
res.view('pages/homepage') // <- in template req.session is undefined
}, //<-- req.session in police middleware is undefined, and lost other custom variables assigned to req (such as req.user defined by passport.js)
// and code in police run after
'/testview': {
view: 'pages/homepage',
}, //<-- req.session is undefined
'/test-1': 'FrontController.testPage', //<-- in this case alright

```

this code produce bug with lost request variables, such as session, user and other

I think this issue maybe related to #4427

Start with config/police.js and config/routes.js, then reproduce the three routes while logging req.session and other request variables in the policy, route handler, and rendered view. Compare the affected view routes with /test-1 and verify that session, user, and other custom request variables remain available throughout the request.
