Michael Eischer d5f86effa1 ls: Explicitly enforce that the user specifies a snapshot ID ...

The help messages suggested that the `ls` command work without
explicitly passing a snapshot ID. However, this was never the case:
without a snapshot ID the command just failed with the error
`Ignoring "", it is not a snapshot id`.

Fixes #2299
