Fix a script object's unique attributes not being correctly set when CloneComponent() is called.
For consistency with the Node class, refer to the ScriptInstance's contained object with "scriptObject" property instead of "object" in AngelScript scripting.
Query the clone component's attribute vector just once.
Safety check in case eg. a script object instantiation would fail and the cloned component would have less attributes.
