Hi,

I followed the steps here #479 (comment)

When I do this:

router = DefaultRouter(
schema_title='Pastebin API',
schema_renderers=[OpenAPIRenderer, SwaggerUIRenderer]
)

I get:
TypeError: init() got an unexpected keyword argument 'schema_title'.

I'm running:
djangorestframework 3.8.2
django_rest_swagger 2.2.0
