The upgrade from 0.11.0 to 0.11.1 broke some environment variable usage.

For example, previously the host would fallback to process.env.CI_SERVER_URL, but with this latest update I receive 401 unauthorized because I rely on the built-in gitlab CI CI_SERVER_URL environment variable instead of the explicit GITLAB_HOST environment variable this CLI is looking for.

For more information on CI_SERVER_URL see https://docs.gitlab.com/ee/ci/variables/predefined_variables.html
