Fixed github name != username issue

[buaazp]

Details:

My github username(gh.user().login) is buaazp while my github name is 招牌疯子, so the remote url is wrong after I fork a repo.

Hello! Thank you a lot for spotting this, and I'm really really sorry for the mistake, that might have many side effects for users ☹

Though, so I can merge it, could you please remove the OSX fix from this commit, and move it into a separate commit and PR?

sure, wait a minute.
