`SimpleVarInfo` sometimes returns a `SimpleVarInfo` with `Int`-type `logp` and creates down-stream errors

MWE

using DynamicPPL # version 0.24.4

julia> si = SimpleVarInfo(Dict(:x => [1, 2 ,3])) # looks good
SimpleVarInfo(Dict(:x => [1, 2, 3]), 0.0)

julia> si = SimpleVarInfo(Dict(:x => 1)) # looks good
SimpleVarInfo(Dict(:x => 1), 0.0)

julia> si = SimpleVarInfo(Dict(:x => [1, 2 ,3], :a => 1)) # bit strange
SimpleVarInfo(Dict{Symbol, Any}(:a => 1, :x => [1, 2, 3]), 0)

julia> acclogp!!(DynamicPPL.ThreadSafeVarInfo(si), -7.899)

It's not Int, it's Real:

julia> d = Dict(:x => [1, 2 ,3], :a => 1)
Dict{Symbol, Any} with 2 entries:
  :a => 1
  :x => [1, 2, 3]

julia> typeof(DynamicPPL.SimpleVarInfo(d))
SimpleVarInfo{Dict{Symbol, Any}, Real, DynamicPPL.NoTransformation}
