Lazy sync with transaction state on destroy

This reverts commit 58410b3d566e6b93c7b71c0eec0fc11ec906b68e.

If we have any implicit commit/rollback callbacks, it is necessary to
add record to transaction explicitly like `:touch_deferred_attributes`.

https://github.com/rails/rails/blob/5f261d04d6f857d49c75124df809adfbd6cd5b5e/activerecord/lib/active_record/touch_later.rb#L9

But I can't find any other implicit commit/rollback callbacks in our
code base at least now.

I think the `self.class.connection.add_transaction_record(self)` line
doesn't cover any behavior.
