catch the error returned by add_repo_status

If add_repo_status returns an error it will eventually be printed to the
user but there won't be any repository information:

    [✘] Error getting status: No branch checked out

Catch the error earlier so we can print the repository name:

    [✘] Error: freebsd-src: Couldn't add repo status: No branch checked out
