MSVertexTracketTool: Fix incorrect sign in tracklet chi squared calculation

The MSVertex Tracklet fitting had an incorrect sign in the chi squared
calculation, causing all tracklet segments to fail reconstruction and
no MS Vertices to be produced. This patch changes the sign to the
correct value, returning the MSVertex performance to its run 2 behavior.
