Fix e2e tests (GoogleCloudPlatform#284)

e2e tests send request against the live app living at
`https://${opts.version}-dot-${opts.project}.appspot.com`;

The test config relies on `opts.project`, which we configure via
an environment variable.

Note that only our tests use $GCLOUD_PROJECT, it is not used in the app.
