d3ce4072 - Only show key backup reminder when confirmed by server to be missing

Only show key backup reminder when confirmed by server to be missing The key backup reminder was being shown too eagerly in cases when we hadn't actually checked with the homeserver on key backup status. This changes to only show the reminder when we're sure a backup doesn't exist. Fixes https://github.com/vector-im/riot-web/issues/13404
