Animation: treat F-Curves with no keys as if muted/not existing.
When normally editing curves, deleting the last keyframe also
deletes the curve. Thus if for some reason it didn't happen,
e.g. maybe due to removing keys directly via Python, skip the
bad curve instead of resetting the channel to zero.
