Follow up to #53373, it seems this assert was broken for empty packages, causing CI issues. It is not necessary. Observed in CI here: #53395 https://buildkite.com/julialang/julia-master/builds/33860#018dc4dc-a603-4ad1-90cf-574540a41720

The default `copysign(x::Real, y::Real)` in `number.jl` works, so the
incorrect method in `rational.jl` isn't needed.
Here is a benchmark of the new version.
```julia
using BenchmarkTools
function foo!(c,a,b)
c .= copysign.(a, b)
nothing
end
N = 1000
@Btime foo!(c,a,b) setup=(c=zeros(Rational{Int},N); a=rand(Int,N).//rand(Int,N); b=fill(-1,N))
```
