buildscripts/resmoke.py run --suites=concurrency_simultaneous jstests/concurrency/fsm_workloads/index_build_abort.js fails to reject the test even though concurrency_simultaneous.yml excludes the requires_replication tag. It turns out each test in https://github.com/10gen/mongo/blob/6cf8b162a61173eb372b54213def6dd61e1fd684/buildscripts/resmokelib/suitesconfig.py#L126 is actually a list[str] because override_suite.tests is a list[list[str]], because it groups the list of tests specified on the command line into a single group to run simultaneously.
