Update media-views and wp.Backbone.View for Backbone 1.1.

* Collection set/add/remove/reset methods now return models, not `this`, so they can no longer be chained.
 * Options passed to Backbone.View's constructor are no longer attached automatically. wp.Backbone.View now does this automatically.

See [27170] for Backbone 1.1 itself.

props gcorne.
fixes #26799.
