They should only be loaded from `app/config/services_test.yml`.
Otherwise we'll have an issue when clearing the cache in prod env:
```
In DefinitionErrorExceptionPass.php line 54:
Class "Doctrine\Bundle\FixturesBundle\Fixture" not found while loading "Wal
labag\AnnotationBundle\DataFixtures\AnnotationFixtures".
```
Also update deps to latest.
Mostly using autowiring to inject deps.
The only tricky part was for import because all producer use the same class and have a different alias. So we must write them down in the service definition, autowiring doesn't work in that case.
Usually:
- if a controller has a constructor, it means injected services are at least re-used once in actions
- otherwise, service are injected per action
And use DI to retrieve services in commands (except for `RedisWorkerCommand` where the container is injected, hard to find a better way, at least for now).
- disable autowiring for Event (because the Entry entity was injected)
- rename `getClient()` for test to `getTestClient()` to avoid error while overriding (from `BrowserKitAssertionsTrait`)
As baggy theme was removed and material is the only remaining theme, we don't need a theme switched anymore.
So:
- move all `*.twig` files from the material theme folder to the root
- remove useless translations
Thanks to the BC compatibility, almost nothing have to be changed.
All changes are related to new bundle version of:
- SensioFrameworkExtraBundle
- DoctrineFixturesBundle
