    backend: really skip VMs with check failure
    
    This seems to be a bug which could cause weird things like "VM not
    responding", but still it was requested to do some task.
    
    Such task could fail without obvious reasons -- and the worst
    thing on this would be that Copr would blame the user for the
    mistake (failed build).
