Error in rails 5.1

I am working on Rails 5.1 application. Getting error when trying to add devise_openid_authenticatable to my Gemfile:

Ah, yup, alias_method_chain was deprecated in 5.0 and is gone in 5.1. The recommendation now is to use prepend and super: https://www.justinweiss.com/articles/rails-5-module-number-prepend-and-the-end-of-alias-method-chain/

I'm not using this gem myself anymore and am not sure I'll have time to fix this in the near future. If you'd be willing to make a PR, I'd review and merge it. Or, if someone is interested in taking over maintainership of this gem, I'd be happy to hand over the reins.

Someone here did it. Is there anything missing in it before being good to merge?
