In order to avoid double assignments of nested_attributes for `has_many` relations during record initialization, nested_attributes in `create_with` should not be passed into `klass.new` and have them populate during `initialize_internals_callback` with scope attributes. However, `create_with` keys should always have precedence over where clauses, so if there are same keys in both `create_with` and `where_values_hash`, the value in `create_with` should be the one that's used.
