Title: remove check access SQL query for guest user

Right now when logged out, this query runs on every logged out request:

```mysql
SELECT * FROM `yii_auth_assignment` WHERE userid=:userid. Bound with :userid=NULL
```

Since there will never be such an entry, the query should be superfluous, no?
