Simplify the way FSMCallbackHolder is wrapped around 'base' algorithms
Instead of explicitly adding the wrapping of FSMCallbackHolder to Transformer, Consumer, Producer, FilterPredicate..., wrap the default base algorithm as defined by the default traits used by Transformer, Consumer, Producer, FilterPredicate...
And to help those Transformer, Consumer... instances which explicitly overrule the default algorithm in order to inherit from GaudiTupleAlg instead, add the wrapping to the underlying GaudiAlg as well.
