Jettoolbox mini aod 706

Adding jet substructure variables into the miniAOD recipe. @arizzi @gpetruc
Well I don't remember changing anything there. However, I change it now in my code to AK4PFchs and I am having this error: 
 No data of type "JetCorrectorParametersCollection" with label "AK4PFchs" in record "JetCorrectionsRecord"
 Please add an ESSource or ESProducer to your job which can deliver this data.
I am using 706_patch1. Should I update the branch anyway?
