Issue #693 - Crash when undo delete rotated segments

1. updateResults should be done after back references synchronization. Sketch multi-rotation uses sketch in the execute(). If the presentation is visualized before the back references are calculated, it leads to crash.
2. synchronize back references should be done after updateResults. List of back references should be set for the updated results. Case: bug scenario, delete, crash.
