The 'repo' field automatically inferred failed, but no error occurred

[ayqy]

Refer to Configuration section:

repo: Your "org/repo" on GitHub (automatically inferred)

I didn't specify a 'repo' field, then ran global installed lerna-changelog, and nothing happened, no CHANGELOG or ERROR

Dived into source and got a 'https://api.github.com/repos/undefined/issues/2'. Set a 'repo' field then it works well.

So, an ERROR message is required as it can't be inferred automatically.

$ lerna-changelog --version

Should be resolved by #102
