Use repository affiliation GraphQL argument

The GitHub GraphQL API now includes a mechanism to choose which
affiliations of the viewer's repositories that you'd like back. This
means that we can remove some logic from the client and instead lean on
the server to do that filtering for us - saving on requests and
bandwidth.
