Evgenii Stratonikov a6c9a337cd [#965] morph: Get rid of container.List invocations
ContainersOf() is better in almost every aspect, besides creating a
session when the containers number is between 1024 and 2048 (prefetch
script does limited unwrapping). Making List() private helps to ensure
it is no longer used and can be safely removed in future.
