When you cast Vacuum a second time on the same units, the location of the pull updates, but the pull speed does not update based on the new distance.

1. Cast Vacuum so that it hits an enemy
2. Before the first Vacuum finishes, cast it again so that the same unit is hit again, but at a different location

Result: The pull location updates so the unit is now sucked towards the center of the second cast. But the pull speed does not update.

Expected: On debuff refresh, the pull speed should update based on the distance between the unit and the new Vacuum location.
