JSExpr warnings

Now that https://github.com/JuliaGizmos/JSExpr.jl/pull/14 is in, I'm getting:

julia> Pkg.test("MeshCat")

Oh no... Yeah, this is easy to reproduce by creating a new package with:

__precompile__()

module Foo

using JSExpr
function foo()
    @js function()
      @new x
    end
end
end

(needs to be a package, not just a module, so it will be precompiled and generate the warning). Looks like https://github.com/JuliaGizmos/JSExpr.jl/pull/14 was the wrong fix

This was fixed.
