prod(ClosedProd(), Beta(1.,1.), Beta(1.,1.)) defaults to UnspecifiedProd

[wmkouw]

Expected behaviour for prod(ClosedProd(), Beta(1.,1.), Beta(1.,1.)) is

Beta{Float64}(α=1.0, β=1.0)

But BayesBase v1.5.0 defaults to UnspecifiedProd;

MethodError: no method matching prod(::BayesBase.UnspecifiedProd, ::Beta{Float64}, ::Beta{Float64})

PreserveTypeProd{Distribution} does not seem to dispatch to the product rule for Beta distributions. I'm not familiar with how this product strategy finds the appropriate Distribution products. Any thoughts anyone?

This was a version mismatch with RxInfer 2.13 and ReactiveMP 3.x.
