Update menu sequence maker alg (ATR-19824)
In the empty menu sequence needed for merging combined chains serially, we need an Input Maker to merge legs from different filters. The empty sequence is only made of one algorithm, the IM, which is then connected to the ComboHypo.
Currently the IM is the AthenaConfiguration.ComponentFactory.CompFactory.HLTTest__TestInputMaker
but should be switched for DecisionHandling.DecisionHandlingConf.InputMakerForRoI
