[#302] pkg/container: Convert nil `UsedSpaceAnnouncement` to nil message
Document that `UsedSpaceAnnouncement.ToV2` method returns `nil` when is called on `nil`. Document that `NewAnnouncementFromV2` method returns `nil` when is called on `nil`. Add corresponding unit test. Signed-off-by: Pavel Karpy <carpawell@nspcc.ru>support/v2.15
