[#1632] node/container: Don't add new container to missed cache record

If container listing cache on node's side is missing (for particular
owner), then updating it as a reaction to successful container creation
leads to potentially invalid cache value for a period of time equivalent
to cache TTL.

Immediately return from `ttlContainerLister.update` method if owner's
container list isn't cached.
