vm_replication_info module fails if both snapshot schedule and replication are unconfigured.

[justinc1]

To reproduce, create a fresh VM. The snapshot schedule and replication will be both unconfigured. Then invoke vm_replication_info for it - it failed with:

VM with both snapshot schedule and replication set was not a problem.

[justinc1]

A CI test for this added to a branch. We need to decide what should module output for such VM.
