Add RefToBase member `holder_' as transient in Reflex dicts.

RefToBase is a templated class with a private memeber holder_ of
reftobase::BaseHolder<value_type>* type. The following type is
not part of any dictionary, thus holder_ is not saved.

Example error generated by ROOT:

Error in <TStreamerInfo::Build:>: edm::RefToBase<reco::Electron>:
edm::reftobase::BaseHolder<reco::Electron>* has no streamer or
dictionary, data member holder_ will not be saved
