I agree. Testing StandbyMode here seems bogus. I thought initially
that the test should perhaps be for InArchiveRecovery rather than
ArchiveRecoveryRequested, but I see that the code which switches to a
new timeline cares about ArchiveRecoveryRequested, so I think that is
the correct thing to test here as well.
Concretely, I propose the following patch.
