Avoid using GraphQL repositories/ownerAffiliations

We should pass affiliations and ownerAffiliations the same
RepositoryAffiliation?[], but ownerAffiliations doesn't currently exist
on GitHub Enterprise. Luckily the default is Owner and Collaborator,
which is what we need in this case (we can simply pass null).
