Fix T39880: Cancelling transforms in Graph Editor does not restore F-Curves to original state

Since autosnap was being applied during the flushing step for various practical reasons,
it wasn't possible to restore keyframes and handles to their original values, as these
would always get overwritten before getting a chance to be written back to the keyframes.
