fix(cli): Tell user to init repo if not initialized when starting daemon

[victorb]

From #631

Had to create PR with branch from ipfs/js-ipfs instead of my fork, since running Sauce Labs would fail otherwise. See https://docs.travis-ci.com/user/pull-requests/#Pull-Requests-and-Security-Restrictions

@diasdavid tests were failing because 1) I set the timeout to one second while Travis is a lot slower to run than that, so removed my manual timeout to use the default one instead, 2) Sauce Labs can't authenticate if the branch comes from a fork, so I had to push the branch to ipfs/js-ipfs instead (opened issue in aegir about this here: ipfs/aegir#76 )

So now everything should work, please review again :)
