[FIX] web_editor: restoreRange on invalid node

In a web editor, add some text, select the text, add a link and
immediately discard the link modal. Traceback.

The traceback is a DOM `IndexSizeError`, that error is thrown when the
boundaries of a DOM Range (`document.createRange`) are outside of the
ranged elements. In this context, the error happens because the element
is empty and the range has an end bound set to the size of the selected
text.

Odoo wrap code does some text node split in order to attach the link
just on the selected text. If it correctly re-set the underlying
structure, it does not update the $(editable) structure used to restore
ranges.
