Thinking about it, how would you feel about going on step further and check all the refs from this remote?

```
                Assert.NotEmpty(repo.Refs.FromGlob("refs/remotes/origin/*"));

                repo.Network.Remotes.Remove("origin");
                Assert.Null(repo.Network.Remotes["origin"]);
                Assert.Empty(repo.Refs.FromGlob("refs/remotes/origin/*"));
```
