Preserve missing project ID error stack trace

[gajus]

I am referring to:

https://github.com/GoogleCloudPlatform/google-cloud-node/blob/1939deaa32298b3cbe123686e5c52f480c1d7ee2/packages/common/src/util.js#L55

Error stack trace is captured at the time of constructing the Error instance.

As a result, the error stack trace does not relate to the origin site of the error, e.g.

Error: Sorry, we cannot connect to Cloud Services without a project ID. You may specify one with an environment variable named "GCLOUD_PROJECT". See https://googlecloudplatform.github.io/google-cloud-node/#/docs/guides/authentication for a detailed guide on creating an authenticated connection.

Consider using the following approach to construct errors:
