When local repository's remotes are like:
* michiels https://github.com/michiels/pencilbox.git
* mine https://github.com/__username__/pencilbox.git
Then run `ci-status` fetches always from 'michiels' remote's build status.
Because there are no 'upstream', 'github' or 'origin' remote names.
So, based on dictionary order, 'michiels' remote is choosed as a main
remote repository and there is no way to fetch 'mine' remote ci-status.
This commit make it possible to choose remote repository's commit
build status with -r option like:
hub ci-status -r mine __commit_sha__
You can also use -v option to retrieve build url:
hub ci-status -r mine __commit_sha__ -v
