Geo - Does not try to unlink file when file path is unknown

What does this MR do?

When cleaning up orphaned registries on a Geo secondary node, 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;

For all of them, we should no try to unlink the file.
