OS X: Does not init with $CIRCLECI_CLI_TOKEN

[eric-hu]

I have export CIRCLECI_CLI_TOKEN=... set in my .bash_profile, but this shows initialized false:

$ circleci me
{
  "initialized": false,
  "outcome": "failed"
}

If I use circleci init, other commands work as expected. I'm not sure where my token is stored when I do that though.

Also--great work on this tool! It's super useful!
