397: fix(upgrade-job): avoid infinite loop when no unhealthy vols have a target r=niladrih a=niladrih

Fixes a bug where if, during data-plane upgrade, `rebuild_result` function finds unhealthy volumes, but none of the volumes have a target, then, the function continues to try to list unhealthy volumes constantly.
