[query] test_hail_in_notebook is not idempotent

[danking]

What happened?

https://batch.hail.is/batches/8083756/jobs/72

test_hail_in_notebook just executed jupyter on test_hail_in_notebook.ipynb. The notebook contains one cell:

import hail as hl
import os
hl.utils.range_table(1).write(f'{os.environ["HAIL_TEST_STORAGE_URI"]}/test_hail_in_notebook.ht')
from helpers import resource
hl.read_table(resource('backward_compatability/1.7.0/table/9.ht')).count()

This is not idempotent because HAIL_TEST_STORAGE_URI is randomly generated once per job not once per attempt. In particular, the job specification itself has this as an environment variable. In the this PR test job, the test job gets preempted and rescheduled. Upon rescheduling, the hail table already exists, causing the test to fail.

The fix is simple: add a random string to the written Hail table file.
