fixing inclusion of legacy L1 MET/sumET in AODs produced by L1TopoSimulationConfig
The L1TopoSimulationConfig is used "standalone" to produce special AODs (currently from RAW, including essentially only L1 objects and decisions) for commissioning purposes. The legacy L1Calo MET/sumET objects were not properly stored so far as their somewhat deviating naming schemes for Aux branches and types were not accounted for. This MR rectifies that.
