Followups to finish migration of repo uri -> name

Created by: sqs

We have deprecated calling the repository name (the value like github.com/foo/bar) the "URI" since April 2018. Now it is just called the repository "name".

There are more things we must do to complete the switch:

• January 2019: remove the GraphQL RepoOrderBy.REPO_URI value from our GraphQL API and make src-cli use REPOSITORY_NAME not REPO_URI

We can't do these until January 2019 per our deprecation policy.
