database: use Repos.List mock for (List|Stream)RepoNames
Created by: keegancsmith
I want to test some code which uses RepoStore and needed a way to mock/fake the response from StreamRepoNames. Instead of adding another mock, we can just reuse the mock for List and minimize the API for mocking.
This is using the potentially "outdated" mocking code we have. However, I don't see an alternative right now. I don't want to make my test depend on the DB, nor do I want to create huge interfaces just for testing.
