I would suggest adding a new method on the `PullRequestListener` interface `initialize(HostedRepository)` and implement this method in `PullRequestBranchNotifier` so you can put this logic there instead. Then you can call `initialize` on all listeners when `getPeriodicItems` is called the first time.

We should not be touching branch protection settings unless `protectBranches` is enabled.
