Morph "NewEpoch" event handling was registered in a closure over
`addNewEpochNotificationHandler` func. That may lead to the data race:
if a shard was initialized before the event registration, everything works
as planned, but if registration was made earlier, it was not able to
include GC handlers since a shard has not called `eventChanInit` yet and,
therefore, it has not registered handler yet.

In previous implementation `Container.Delete` operation caused local
node's cache invalidation (container itself, eACL and listings). Any
subsequent `Container.Get` operation reversed invalidation. Given the
low latency sensitivity of deleting a container, there is no need to
touch the cache. With this approach, all pending deletion operations on
the node via the NeoFS API protocol will be delayed by the cache TTL.
Do not call cache invalidation ops in `morphContainerWriter.Delete`.
Remove no longer needed `InvalidateContainerListByCID` and
`InvalidateContainer` methods.

node from current epoch -- it is not. Then it tries to find if
key belongs to container node from past epoch and it throws
