Fix T40548: After canceling, F-Curve handlers don't go back to original position.

Handle vectors for the initial location were only stored when the handles are actually
selected for transform. When only the master vertex is moved this can still affect
the handles though, since they are constraint to one side of the master vertex.

Now the handle data is stored regardless of whether handles are included in the transform,
so on cancel their location is reset correctly as well.
