Title: Allow access to Serializer's visitors getter

Since 1.0.x, I can no longer do

```php
get('jms_serializer.xml_serialization_visitor')->setDefaultRootName('a_root_name');
```

because `jms_serializer.xml_serialization_visitor` is now private.

With this PR I could just do

```php
get('serializer')->getSerializationVisitor('xml')->setDefaultRootName('a_root_name');
```
