1. Open CKEditor demo in Webkit Browser
2. Insert a link using the link button.
3. Highlight the link.
4. Press the unlink button.

Observe that is removed but inspecting the source of the editor show that an empty <a></a> has been left at the end of the previous link pointing to where the previous link was pointed.

If you check the source after unlinking you will find: <a data-cke-saved-href="http://abc.com" href="http://abc.com"></a> in Webkit and
<a data-cke-saved-href="http://abc.com" href="http://abc.com" /> in Opera.
Other browsers seem to work fine. They don't leave nay empty <a> tags.

This might cause problems for users who use getSnapshot() method as it returns empty <a> as well.

Issue has been reproducible from CKEditor 3.0.
