I think it's better to leave that for later. If we see that this becomes a problem, we could think about possible solutions. Let's try to keep the scope of this change from growing too much.

I suppose it doesn't matter if they share the map, but the test does not need to verify that they do, or that a `CSRIssueBot` for a certain `IssueProject` is able to look up a `PullRequestBot` for a different IssueProject. The test should only verify that the relevant PullRequestBots are available.
