prefer `put(std::unique_ptr<T>)` over `put(T*)`
Stop using the to-be-deprecated (and to-be-removed) put(T*)
-- see gaudi/Gaudi!1086 (merged) -- and prefer the (already existing for long) put(std::unique_ptr<T>)
.
Should be merged prior to gaudi/Gaudi!1086 (merged), i.e. gaudi/Gaudi!1086 (merged) is waiting for this one.
