disabling deep option with toArray() drops relations in result

Using the toArray() on a Doctrine_Record object with the deep option set to true (default) correctly converts the whole object to an array including the relations.
But when the deep option is disabled the relations are not converted to array's (as expected) but they are lost, I would expect them to still be there in their original form (objects).

I've attached a fix. Another solution would be to add a flag that disables deep array conversion but enables relation persistence.
