Leonard Lyubich 70ffdf3478 [#1247] object: Return NOT_FOUND and ALREADY_REMOVED statuses
Replace `ErrNotFound`/`ErrAlreadyRemoved` error from
`pkg/core/object` package with `ObjectNotFound`/`ObjectAlreadyRemoved`
one from `apistatus` package. These errors are returned by storage
node's server as NeoFS API statuses.
