Title: Fix dashboard group names using parameters.

As pointed in sonata-project/SonataUserBundle#97 we currently can't define a dashboard group using a parameter and then configure that group in

```sonata_admin:
dashboard:
groups:
sonata_user:
label: Some custom label
#this custom configuration will prevent sonata_user panel
#from being displayed
```

Indeed, in the top level dashboard group configuration, the group names are resolved, but aren't when defining an admin service (in the previous example, we have "sonata_user" on one hand and "%sonata.user.admin.groupname% on the other hand).

This should fix this issue more cleanly that the proposed sonata-project/SonataUserBundle#97 PR.
