fix crash when switching away from node tool while redrawing after a handle move; the end_forced_full_redraws in the handle_ungrabbed may become invalid because the nodepath is destroyed while in screen update triggered by update_repr, and it is redundant anyway because update_repr does its own end_forced_full_redraws
