Fix `scope_for_create` to do not lose polymorphic associations
This regression was caused at 213796fb due to polymorphic predicates are combined by `Arel::Nodes::And`. But I'd like to keep that combined because it would help inverting polymorphic predicates correctly (e9ba12f7), and we can collect equality nodes regardless of combined by `Arel::Nodes::And` (`a AND (b AND c) AND d` == `a AND b AND c AND d`). This change fixes the regression to collect equality nodes in `Arel::Nodes::And` as well. Fixes #31338.
