Do not assume Condition payload contains a YAML::Node

With LHCb!3765 (merged), some changes introduced by !378 (merged) do not work anymore as the were relying on how the (inefficient) conversion from Condition to YAML::Node was implemented.

I'm reverting that bit of code as it's anyway useful only when the algorithm is migrated to Gaudi::Functional.
