MVC - allow data property to be predefined on the prototype of StatefulModel

[ben hockey]

StatefulModel? assumes an object is passed to the constructor with a data property. i'm using composejs (​https://github.com/kriszyp/compose) to compose a temporary constructor with all the data mixed in to the prototype and then calling the constructor with no params. this works fine with all of dijit but StatefulModel? won't allow this pattern.

this small change would fix it.
