els_VIDTrigMvaValue empty 2016 94x miniaodv3 cms4

[aminnj]

E.g., /hadoop/cms/store/group/snt/run2_data2016_94x//DoubleMuon_Run2016F-17Jul2018-v1_MINIAOD_CMS4_V10-02-04/merged_ntuple_1.root
has empty els_VIDTrigMvaValue branch

MC seems fine

I don't think we ever used the "Triggered MVA", and it doesn't exist after 2016, so I think this is fine, no? Does the untriggered MVA look OK?

I didn't flesh out the original error.
els_VIDTrigMvaValue and els_VIDNonTrigMvaValue are empty
but els_VIDSpring16GPMvaValue looks fine
