Update to 712 HLT ConfDB template for 72X

It adds a filter against possible fake hltGoodOnlinePVs in the new Top PAG paths, on top of the commit of @Martin-Grunewald which migrates the Run2 menu in 72X to the CMSSW_7_1_2 ConfDB template.

This pull request is on top, and supersedes, #4596, which should therefore get closed (or at least merged before this one).
