OS X: Does not init with $CIRCLECI_CLI_TOKEN

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.
