Commit Freetext on cloned edition adds textdiv to original Text sequence

[stevewh]

In a cloned edition change anything cause copy on save to propagate up the containment hierarchy scl->linephysical->TextPhysical which replaces the top container in the cloned edition. This works for scl but the tok->textdivision->Text has a bug where textdivision gets added to the original edition Text sequence and a new Text Sequence is not created and use to replace the original in the cloned edition.
