graph-cli build: Improve Module Load Failure Handling

[dOrgJelli]

Currently if there's a problem when loading the module, graph-cli only reports back the message field of the error object, which leads to lost information. Here's an example:
console.log(error):

import gql from "graphql-tag";
       ^^^

SyntaxError: Unexpected identifier
    at new Script (vm.js:80:7)
    at createScript (vm.js:274:10)
    at Object.runInThisContext (vm.js:326:10)
    at Module._compile (internal/modules/cjs/loader.js:664:28)
    at Object.Module._extensions..js (internal/modules/cjs/loader.js:712:10)
    at Module.load (internal/modules/cjs/loader.js:600:32)
    at tryModuleLoad (internal/modules/cjs/loader.js:539:12)
    at Function.Module._load (internal/modules/cjs/loader.js:531:3)
    at Module.require (internal/modules/cjs/loader.js:637:17)
    at require (internal/modules/cjs/helpers.js:22:18)

VS

console.log(error.message):
