When fpBalancerShouldReturnRandomMigrations failpoint is enabled (which happens in all of `._with_balancer.` suites), we may select a migration for an unsharded collection without removing the involved shards from the availableShards list. Therefore, we will probably use the same shards to migrate chunks on the same balancer round.
This is only happening on our tests because the failpoint is only enabled there.
