Another even simpler version that we use in the function already (e.g.
right above for blockingHAResources) is to just fallback to an empty
array, i.e.

let comigratedHAResources = migrateStats['comigrated-ha-resources'] ?? [];
if (comigratedHAResources.length) {
...


Either way, the fix should also be done for checkLxcPreconditions(...),
because there it's missing the check too.
