[#1632] node/container: Update GET cache on successful removal

Browse source 
In previous implementation storage node responded with the removed
container up until cache invalidation due to TTL. In order to avoid
false-positive responses node should update its cache on `DeleteSuccess`
events.

Make node to call `handleRemoval` method of the container cache which
leads to subsequent `apistatus.ErrContainerNotFound` errors.
