[pbs-devel] [PATCH proxmox-backup 1/3] fix #3331: improve progress for last snapshot in group

especially for the last group, without this the progress would report:

"percentage done: 100.00% (1 of 2 groups, 1 of 1 group snapshots)"

instead of the more logical

"percentage done: 100.00% (2 of 2 groups)"

Notes:
    note: alternatively, we could only do this special case for the very last
    group, and leave the other groups to display:
    
    "percentage done: 50.00% (1 of 4 groups, 1 of 1 group snapshots)"
    
    which looks a bit weird, but would mean that the format stays consistent over
    the whole log, instead of switching between groups+snapshots and just groups.
    
    see also next patches, which makes it a bit more informative/readable IMHO
