Guarantee sumPt2 presence in PrimaryVertices container
Correct rewriting of the PrimaryVertices container during PV sorting so that sumPt2 aux temp is always created. Previously the sumPt2 aux data was absent if no PV was reconstructed and only a dummy vertex was present in the PrimaryVertices container. This MR addresses ATLASRECTS-7186 and breaks frozen Tier0 policy, although events without primary vertices are very rare.
