Saves any new associated records, or all loaded autosave associations if
:autosave is enabled on the association.
In addition, it destroys all children that were marked for destruction with
mark_for_destruction.
This all happens inside a transaction, if the Transactions module is included
into ActiveRecord::Base after the
AutosaveAssociation module, which it does by default.
