CLI-1412: [auth:login] PHP warning

[danepowell]

Motivation

Fixes CLI-1412

Proposed changes

I suspect the root cause is keys being an empty array while there’s an active key, which passes the schema validation but obviously isn’t valid.

In troubleshooting this I found a related bug, which is that running auth:logout creates an invalid schema.

The fix in both cases is to adjust the schema validation logic.
