[PATCH 3/5] txn: fix execution order of commit triggers

[Konstantin Osipov]

> Both commit and rollback triggers are currently added to the list head.
> As a result, they are both run in the reverse order. This is correct for
> rollback triggers, because this matches the order in which statements
> that added the triggers are rolled back, but this is wrong for commit
> triggers. For example, suppose we create a space and then create an
> index for it in the same transaction. We expect that on success we first
> run the trigger that commits the space and only then the trigger that
> commits the index, not vice versa. That said, reverse the order of
> commit triggers in the scope of preparations for transactional DDL.
