b358229834* Use ActiveRecord::Result#to_ary instead of deprecated to_hash They do the same thing, and to_hash has been removed from Rails 6.1 * Explicitly name polymorphic indexes to workaround a bug in Rails 6.1 cf. https://github.com/rails/rails/issues/41693 * Fix incorrect usage of “foreign_key” in migration script * Use `ActiveModel::Errors#delete` instead of deprecated clear method * Fix link headers tests on Rails 6.1 Rails 6.1 adds values to the Link header by default, thus it is not a LinkHeader object anymore. Fix the test to parse the Link header instead of assuming it is a LinkHeader.
