NullPointerException if the database has no keyspaces

[weideng1]

See the following output. This database is having some issues with cqlsh connection and download-scb. astra-cli could have better error handling and outputs something like: "the database is in a bad state. DevOps API call on xxx is broken", which would be more meaningful to the end users.
