Hi @domm

Please review the PR.
It proposed fix to the error "Skipping invalid git remote github" as below:

    [DZ] beginning to build Plack-App-ServiceStatus
    [DZ] guessing dist's main_module is lib/Plack/App/ServiceStatus.pm
    [VersionFromModule] dist version 0.903 (from lib/Plack/App/ServiceStatus.pm)
    [Repository] Skipping invalid git remote github
    [CheckChangeLog] [CheckChangeLog] OK with Changes
    [DZ] writing Plack-App-ServiceStatus in Plack-App-ServiceStatus-0.903
    [DZ] building archive with Archive::Tar::Wrapper
    [DZ] writing archive to Plack-App-ServiceStatus-0.903.tar.gz
    [DZ] built in Plack-App-ServiceStatus-0.903

According to the plugin "Dist::Zilla::Plugin::Repository":

    git_remote
    This is the name of the remote to use for the public repository (if you use Git). By default, 
    unsurprisingly, to origin.

Many Thanks.
Best Regards,

Hm, the real problem is that this dist has two remotes (github and a private one). On the machine I did the most work the origin is set to the private repo, and github is added as a second remote.

But as per default a clone from github will set github as origin it probably makes more sense to use github as the default (origin) repo.

Thus your MR makes sense and is now being applied (but I'll have to change my local gitconfig so future releases will point to github and not the internal repo)
