Style/AccessorGrouping safe autocorrect results in invalid code

[a-lavis]

Sometimes the Style/AccessorGrouping cop, which is marked as a safe autocorrect, corrects to incorrect code.

---

Expected behavior

When running rubocop -a foo.rb where foo.rb is the following file:

# frozen_string_literal: true

class Foo # :nodoc:
  attr_reader :one

  OTHER_ATTRS = %i[two three].freeze

  attr_reader(*OTHER_ATTRS)
end

I expect Style/AccessorGrouping to either not safe autocorrect, or for it to safe autocorrect to:

# frozen_string_literal: true

class Foo # :nodoc:
  OTHER_ATTRS = %i[two three].freeze

  attr_reader :one, *OTHER_ATTRS
end

Actual behavior

It safe autocorrects to:

# frozen_string_literal: true

class Foo # :nodoc:
  attr_reader :one, *OTHER_ATTRS

  OTHER_ATTRS = %i[two three].freeze
end

This code is invalid, because OTHER_ATTRS is used before it is defined.

Steps to reproduce the problem

Run rubocop -a foo.rb where foo.rb is the above file.
