Complex object cannot be removed if link object is deleted

[abereziny]

Let say we have:

1. Complex object with id 123
2. Link object with id 123-link
3. Link object with id 123-link was deleted

Steps:

1. Try to delete complex object

neofs-cli --config wallet_config.yml object delete --rpc-endpoint '<endpoint>' --wallet '51bb4c44-f545-4967-83e7-d36eb166e513.json' --cid '<container_id>' --oid '123'

Expected Behavior

It should be possible to still delete object

Current Behavior

failed to get linking object's header: read object header via client: status: code = 2052 message = object already removed
