Python `create_vaults_from_input.py` example script fails on Windows

[ag-adampike]

In Windows environments, getMyUUID() catches an error on every run of the script, even after recently signing in. The response from the subprocess.run implementation of 1Password CLI seems to include a non-zero return code in every case, so the script exits here:

I've not yet been able to work out why this is an issue for Windows, but it's easily reproduced. The error message consistently includes account not signed in.
