retry intermittant failures on reinstated tests

[Ben-PH]

some tests were reinstated in #3507

the reinstated tests occassionally fail for reasons outside the scope of what is being tested (#3509) . This is handled in CI through our use of cargo nextest with automatic retries, but locally, you could run into some false fails.

Until I find an upstream fix (i.e. you can run cargo test -F testing, and things just work), the downstream sollution is to retry those tests manually, or use nextest run --retries 5.

A intermittant fix should allow cargo test to run nextest run --retries 5
