Check for empty ns list before checking nslist[0]

Browse Source 
In determining whether a backup includes all namespaces, item_collector
checks for an empty string in the first element of the ns list. If processing
includes+excludes results in an empty list, treat this as another case
of a not-all-namespaces backup rather than crashing velero.
