To increase test coverage of moving around unsharded collections, we want to extend the suites and FSMs that are using the `balancerShouldReturnRandomMigrations` to also randomly move around unsharded collections.

This should be implemented keeping in mind that many of our tests have a small number of shards, and we would like to ensure that both chunks and unsharded collections are being moved throughout the test.
