Closing div is inserted into DOM when Initializing editor with a <textarea> in it.

[doncx55]

This problem happens in 3.4.2 and also 3.1, so it must have been around for a while.

When CKEditor is initialized and the contents include a <textarea> form tag, then CKEditor inserts and extra </div> into the DOM.

This renders the editor useless, as the outer form is disabled by the insertion. Also, it makes it impossible to edit an existing form with a textarea in it.

See examples:

​http://www.coxe.org/CKBugDemo/FormTest2.html (*exact* same, but with textarea element in editor)
