### Objective:
To fix `Permissions Tests Part 1 (1.18.x, ubuntu-latest)`
### Strategy:
To make test more reliable, it has been isolated in folder `A` and `B`,
letting other tests to properly pass. And if new failure is observed, it
will be either in folder `A` or `B` for `iamPolicies.ts` and
`bucketWritePrefixOnly.ts` respectively.
### Root cause:
`iamPolicies.ts` and `bucketWritePrefixOnly.ts` are not stable tests
when running together with other tests, some sort of racing condition
that can be improved by isolating them.
### All tests are passing, same code:
