fix(minor typo)

Fix detection of successful batch allocations

This PR restores older behavior of detecting successful batch
allocations (04d86ffd). This has the
side effect that we correctly filter desired status stop but not
successful batch allocations and create their replacements.

This is currently broken and should be removed from docs until a fix is
released.
