Update curve animation data when loading UndoCurve -- fixes memory corruption

when starting playback after undo-ing topology changes

The simpliest way was to change data at which undoCurve_to_editCurve and
editCurve_to_undoCurve works from curve to object. Maybe it's not very
cool, but still better than moving curve animation handlers outside of
editcurve module.
