Protect object SF retrieval in data
Some of the analysis code are currently retrieving the object scale factors as decorations but those are not present in data.
leading to crash like
FinalVarsbbttAlg ERROR SG::ExcBadAuxVar: Attempt to retrieve nonexistent aux data item `::tau_effSF_Loose_NOSYS' (902).
Protecting those behind some isMC property should hopefully solve the failure with minimal adaptations required to the existing algorithms
