fix: cut collapsed table cell won't crash the editor

[saif-ellafi]

Currently, calling a cut action on a table cell will completely crash the table editor. it leaves the document in a state where a table has no cells, rather then deleting it completely.

Not sure if this approach is the best, but gets the job done. Any ideas welcome.

Warning: This won't retroactively fix editor states where the Document has already been broken prior to this patch.
