Moore fails in lhcb-run3-cleanup

Moore fails in the lhcb-run3-cleanup nightly slot with errors related to Track. One is pretty obvious: I removed the L0Candidate attribute and don't see how Moore would need that. See https://lhcb-nightlies.web.cern.ch/logs/build/nightly/lhcb-run3-cleanup/6/x86_64-centos7-gcc9-opt/Moore/

The relevant changes are those with lhcb-run3-cleanup label in https://gitlab.cern.ch/lhcb/Rec/-/merge_requests?label_name%5B%5D=lhcb-run3-cleanup https://gitlab.cern.ch/lhcb/LHCb/-/merge_requests?label_name%5B%5D=lhcb-run3-cleanup https://gitlab.cern.ch/lhcb/Phys/-/merge_requests?label_name%5B%5D=lhcb-run3-cleanup .

At PAC we decided to move these MR into master as soon as they pass the RTA validation, to avoid having to manage MR conflicts for too long. The details can be discussed in master. Please let me know what I should do to make Moore happy.
