Draft: Fix Draft_Edit sketch issue

[Roy-043]

Draft_Edit did not work on a wall sketch after reopening a file.

I have removed the import Sketcher statement from the update_object_from_edit_points function. Maybe it was inserted in an attempt to fix this issue, but it does not seem to be required.
