Rather than skipping our endEdit() call in libedit, we need to parameterize whether we want the shape open/closed. Closed will remove the last segment if it lands on the first point. We don't want that but we do want to remove the last point if it duplicates the second to last (in the case of double-clicking) Fixes https://gitlab.com/kicad/code/kicad/issues/10334 (cherry picked from commit 55020c2b8950be14a46b438f6d080eefc040df19)
