Rework the TTI scenario

--> make it run with Be5D10D
--> removing unnecessary steps in runthematrix (reco- harvesting)
--> calling explicitely localreco to be run (as it's supposed to be in MC prod)
--> rework a bit the customize for making it more standard
tested with runTheMatrix.py --what upgrade -l 12800

according to the summary it seems that maybe there is a merging pb with a recent change in combine_customs
related to hcal phase2 and ecal time...
