[IE]Paste doesn't work on selected word.

[Artur Delura]

Prerequisites: Copy some text into clipboard.

1. Open some sample with inline editor (I opened ​http://presets.ckeditor.dev/4.4.0/basic/ckeditor/samples/tabindex.html).
2. Focus editor.
3. Select some word (doesn`t matter whether using keyboard or mouse).
4. Open context menu (mouse right click or keyboard menu button).
5. Select "paste".

Actual result: There is error in console

IE9, IE10: SCRIPT5022: DOM Exception: INDEX_SIZE_ERR (1) ckeditor.js, line 379 character 513 SCRIPT5007: Unable to get value of the property 'type': object is null or undefined ckeditor.js, line 139 character 112

IE11: SCRIPT5022: IndexSizeError File: ckeditor.js, Line: 382, Column: 513

Please note: Same effect in FULL ALL build
