Fix server key warning (#4973)

Browse source 
The current canary version shows the following warning in development mode:

```log
Warning: Each child in an array or iterator should have a unique "key" prop. See https://fb.me/react-warning-keys for more information.
    in script
    in NextScript
    in body
    in html
    in Document
```

This PR adds proper keys to the devFiles on the server.
