#29130: wp.mce.View.extend no longer working as expected

 I have a plugin that uses `wp.mce.views.register` to parse shortcodes and
 render a placeholder in the wysiwyg editor.

 In 3.9.1, I was using the syntax `View: wp.mce.View.extend({...})` to
 create the view that is rendered in the editor, but this no longer works
 under 4.0. The default wp.mce.View object is used instead.

 In 4.0 beta, I I instead need to use `View: _.extend( {}, wp.mce.View,
 {...})` to get the same effect that I used to get using
 wp.mce.View.extend. The underscore based syntax is however not backwards
 compatible with 3.9.1, where it breaks with the javascript error "g.View
 is not a constructor".
