Fix circular `autosave: true` Use a variable local to the `save_collection_association` method in `activerecord/lib/active_record/autosave_association.rb`, instead of an instance variable. Prior to this PR, when there was a circular series of `autosave: true` associations, the callback for a `has_many` association was run while another instance of the same callback on the same association hadn't finished running. When control returned to the first instance of the callback, the instance variable had changed, and subsequent associated records weren't saved correctly. Specifically, the ID field for the `belongs_to` corresponding to the `has_many` was `nil`. Remove unnecessary test and comments.
