Rails/ActiveRecordCallbacksOrder autocorrect infinite loops if lines contain comments

[ghiculescu]

Given this file:

# app/models/foo.rb
class Foo < ApplicationRecord
  after_create :thing1
  before_validation :thing2 # comment
  after_create :thing3 # comment 2
  before_validation :thing4
end

Running rubocop -a hangs forever. If you interrupt it, the file will look something like this:

If you remove the comments, it autocorrects fine:

class Foo < ApplicationRecord
  before_validation :thing2
  before_validation :thing4
  after_create :thing1
  after_create :thing3
end

---
