cert-sync fails to add multiple certs with the same name from the trusted cert store

[emerconnelly]

Steps to Reproduce

1. add two self-signed CA certs with the same name to the local trusted cert store
2. run cert-sync /etc/ssl/certs/ca-bundle.crt

Current Behavior

When running cert-sync /etc/ssl/certs/ca-bundle.crt, the cert with the same name is "re-added" every time the command is run.

Expected Behavior

When running cert-sync /etc/ssl/certs/ca-bundle.crt, I expected the cert to be added once. Upon running the command each time there after, it should no longer add the cert again.
