getNameSchemaService removed in 8afe7bb

for the other point, actually the TextLine\Type is instantiated just to give meaningful return values to inner service methods so that we can test that the inner service method is called and that its return value is returned by the SignalSlot version of the service. I might use Null\Type instead or a mock of the abstract class `eZ/Publish/Core/FieldType/FieldType`. But in any case, I need an object so that I can do a `===` comparison between the return value of the inner service method and the return value of the signalslot service method.
