Pop/Go Modules Bug

This repo showcases a bug where, in Go 1.11.beta3, Go modules refuse to pick a version of Pop greater than 4.5.9.

Assuming you have the beta installed and available as go1.11beta3 running the test.sh file should reproduce the problem.

The Problem In Brief

Even when specifying a go.mod file with a specific version, greater than 4.5.9, Go modules will not pull that version and instead keeps stopping at versio 4.5.9

package main

import (
	"fmt"

	"github.com/gobuffalo/pop/soda/cmd"
)

func main() {
	fmt.Println(cmd.Version)
}
