drop InitializeMuonCaloEnergy and MergeMuonCaloEnergyContainers algos
The InitializeMuonCaloEnergy algorithm is (was) a very awkward piece of code: All it did is recording an empty container in StoreGate, apparently to be populated by another algorithm. Grep'ing through git I found the only other code that touches this container is the MergeMuonCaloEnergyContainers algo. But there is no trace of that algo in any jobOption file. It is never scheduled. I don't know if this a half-implemented solution or a half-dropped solution or if there is a usage that my git-grep didn't find. At least the q221 and q431 test run happily with these code removed.
