req.logout() Change in new version of passport

[asgomda]

The logout route was previously:

router.get('/logout', (req, res, next) => {
req.logout();
res.redirect('/')
})

should be modified to:

router.get('/logout', (req, res, next) => {
req.logout((error)=>{
if (error) {return next(error)}
res.redirect('/')
});
})
