Title: consistently handle `undefined` being passed to the model constr

This adds more consistent behavior to the Model constructor when passing `undefined`. Presently, if `undefined` is passed to a Model constructor and that model has defaults set, initialize will be passed the defaults object as its first argument (see [#1545](https://github.com/documentcloud/backbone/pull/1545#issuecomment-7738605) for more detail). This behavior is *not* present when nothing is passed to the Model.
