workload: run random causes panic: testing: Verbose called before Init

[awoods187]

I was testing the idea in #44713 with run random when I hit a panic in the workload generator:

export CLUSTER=andy-3node
roachprod create $CLUSTER -n 4 --clouds=aws  --aws-machine-type-ssd=c5d.4xlarge
roachprod run $CLUSTER --  "sudo umount /mnt/data1; sudo mount -o discard,defaults,nobarrier /mnt/data1/; mount | grep /mnt/data1"
roachprod stage $CLUSTER:1-3 cockroach
roachprod stage $CLUSTER:4 workload
roachprod start $CLUSTER:1-3
roachprod adminurl --open $CLUSTER:1
roachprod sql $CLUSTER:1
CREATE TABLE t0(c0 INT);
select * from t0;
  c0
------
(0 rows)

Time: 5.039517ms

Then, in another shell, I tried to populate this with data:

roachprod run $CLUSTER:4 "./workload run rand --table t0 --db defaultdb {pgurl:1-3}"

panic: testing: Verbose called before Init
