$PATH lost to Standard Bundles

[geowa4]

It appears the container's PATH is messed up when running container bundles through Relay. I was using the golang:onbuild image to quickly prototype my bundle. In it, I placed some simple scripts for each of my commands. For example, I would have /usr/local/bin/custom-command with contents

#!/usr/bin/env bash
set -e

/usr/local/bin/go-wrapper run custom-command

The error message I get back is

+ exec app private-list
/usr/local/bin/go-wrapper: 89: exec: app: not found

app is an executable located in $GOPATH/bin, which is added to $PATH here: https://github.com/docker-library/golang/blob/ce284e14cdee73fbaa8fb680011a812f272eae2e/1.6/Dockerfile#L21. If I switch my shell script to execute the Go binary directly (/go/bin/app custom-command) all works well.

I have not checked if other environment variables are lost.
