BUG Fixing model not being set before populateDefaults()

Browse Source 
In cases where a getter on a DataObject calls getComponent() or
other relational getter, $this->model won't have been set at
this point, and a fatal error is triggered.

This fixes it so $this->model is set *before* populateDefaults()
in DataObject::__construct() and the getters can operate normally.
