The behaviour of asking for the earliest-local timestamp (-4) when Tiered Storage is not enabled is to return the earliest timestamp (-2). We need to define the behaviour of asking for the latest-tiered timestamp (-5) when Tiered Storage is not enabled. In such a situation, -5 should return the same as -2. The reason we want to return the same rather than 0, for example, is that we should be returning an offset which is in the current we won't return any offset. This behaviour is what we do already if someone asks for a timestamp greater than that of a recently committed record (and would thus ask for something outside the bounds of the log).
