sanctuary: secret version already destroyed

@rjw57 I haven't had time to try and look at what is causing this, but it has happened a couple of times now. When I update a document-type secret in 1Password and then run sanctuary sync I get the following error. If I re-run the command after a few seconds it works with no issue.
