undoing changes

--------------------------+-------------------
 When a post has one or more wpviews, it is possible to get the editor in a
 state where previous changes cannot be undone via ctrl+z / command+z.

 To reproduce,

 1, Create and save a post with at least one gallery and a block of text
 before and after.
 2. Cut some of the text and paste it somewhere.
 3. Try to undo twice.

 Expected:
 The pasted text to be removed and the cut text to be restored.

 Actual:
 The pasted text is removed, but the cut text is not restored.

 This occurs when wp.mce.views.render() is called and updates the DOM.

 See [https://core.trac.wordpress.org/browser/trunk/src/wp-
 includes/js/tinymce/plugins/wpview/plugin.js?rev=27408#L143 line 143] in
 the wpview plugin.

 The first undo correctly removes the pasted text
