InvalidAWSJobStoreTest::testInvalidJobStoreName is flaky

[unito-bot]

In https://ucsc-ci.com/databiosphere/toil/-/jobs/56706 I saw the testInvalidJobStoreName fail during teardown in _cleanUpExternalStore with a weird error about a missing/vanished temp directory:

ERROR src/toil/test/jobStores/jobStoreTest.py::InvalidAWSJobStoreTest::testInvalidJobStoreName - FileNotFoundError: [Errno 2] No such file or directory: '/tmp/tmplll6r6qy'

We probably need to make the teardown more robust.

That link doesn't work for me, but did you merge with the primary branch recently? I fixed this in https://github.com/DataBiosphere/toil/pull/4700/files#diff-a9da500acc99663546a84f87882f356f76adab635c96ecf14fa50f3b8475fc84R1150

This should be fixed by #4700
