Minor fixes for UFO track association
While testing !39460 (closed), we noticed some small issues with the track association for UFOs, which are fixed here.
The first is a small typo in the TrackCaloCluster_v1 code, which doesn't correctly get the track links.
The second is related to how the track thinning works for UFOs for derivations. In the UFO implementation, UFOs which are associated with exactly one PFO (taste == 0) do not have an associated track link, since they only have the associated PFO link. To make sure that these tracks are included in the thinning, I have changed the thinning to include the associated track for the PFO.
