Remote following success page (#4129)

* Added a success page to remote following
Includes follow-through links to web (the old redirect target) and back to the remote user's profile

* Use Account.new in spec instead of a fake with only id
(fixes spec)

* Fabricate(:account) over Account.new

* Remove self from the success text
(and all HTML with it)
