Block when creating the renewal timer, rather than doing it in a goroutine. This fixes an issue where startRenew and stopRenew are called very closely together, and due to lock ordering, stopRenew may be called before startRenew, resulting in the appearance that the renewal timer has been stopped before it has actually been created. This is only an issue in tests, as that is the only place stopRenew is actually used. In particular this issue manifests in TestGetCertiifcate sub-tests, where a httptest server reuses a port across two of the sub-tests. In this case, the renewal calls end up creating dirty state for the subsequent test, which can cause confusing behavior (such as attempting to register an account twice.) Another solution to this problem would be introducing a bool, protected by renewalMu, which indicates if renewal has been halted, and to check it in startRenew to check if stopRenew has already been called, which would allow us to continue calling startRenew in a goroutine and relying on renewalMu locking for ordering. That said I don't see a particularly strong reason to call startRenew concurrently, so this seems like the simplest solution for now.
