e2e tests doesn't support nextjs

## Background Information
Right now, the tests never finish when NextServer is properly loaded. The "workaround" is to set a wrong path so NextServer never tries to boot. But this leaves the following error:

```
[Nest] 27924 - 07/18/2022, 11:19:56 AM ERROR [ViewService] Failed to load NextServer
[Nest] 27924 - 07/18/2022, 11:19:56 AM ERROR [ViewService] Error: Could not find a production build in the '/Users/msantos/workspace/aletheia_fact/.next' directory. Try building your app with 'next build' before starting the production server. https://nextjs.org/docs/messages/production-start-no-build-id
```

## How
The solution seems to be mocking the ViewService so the NextServer is never booted
