CaloTPCnv+TPTools: Workaround for problem with *WithKey and TrigSerializeTP.
Adjust CaloTPCnv converters so they won't give an error if persToTrans is called instead of persToTransWithKey. This prevents a crash when the converters are called from TrigSerializeTP. This will eventually be fixed in TrigSerializeTP, after which this workaround can be removed.
Also need to temporarily remove the final qualifier from TPConverterWithKeyBase::persToTrans.
