Missing extension in devise migration (invitable)

[woyzeck]

The application template for devise generates a migration for the invitable module (if selected as an option), but the generated file lacks the rb-extension.

The generated file is...
20140422160630_devise_invitable_add_to_users

...while it should be...
20140422160630_devise_invitable_add_to_users.rb

This bug prevents the migration from being executed and thus leads to the following error upon login:
NameError - undefined local variable or method `invitation_token' for #User:0x007faebcf6e830:

This is an issue with Rails 4.1.

See scambra/devise_invitable#447

It's been reported for devise_invitable but I don't believe they're released an updated gem.

Closing this issue as I believe it is resolved in the most recent devise_invitable release. Someone will have to restore the option in the rails_apps_composer gem, though:
