WL-123 Use existing notification view/model for auto-enrollment

@chrisndodge @afzalwali Kindly review the changes for WL-123. I have used the exiting notification view/model for auto-enrollment.

Thanks
I think you could further simplify the code to remove the early return (and the duplicated lines of code from 248-256).

Just first do the special code in lines 259-264 if the type is not 'confirmation'. Then create the model, view, and render.
