Issue with global version reporting

Describe the bug When running idyll --version in a directory outside of an idyll project, I see this:

$ idyll --version

  Using version undefined (installed globally).

  To install local dependencies in an Idyll project that
  you've cloned from GitHub, run `npm install`.

To Reproduce Steps to reproduce the behavior:

1. Install the latest idyll globally (npm i -g idyll@latest)
2. Navigate to a folder that does not contain an idyll project
3. Run idyll --version
4. See error

Expected behavior The correct version should be printed.
