Does not try to unlink file when it not possible

When cleaning up registries, there are some cases
where it's impossible to unlink the file:

1. The replicable record does not exist anymore;
2. The replicable file is stored on Object
   Storage, but the node is not configured to use
   Object Store;
3. Unrecognized replicable type;
