We extended the "aggregation_repeat_queries" suite to also force multiplanning after discovering SERVER-88932. SERVER-88932 was originally discovered by property testing which is much quicker and is now committed, so the issue would've been caught without the passthrough.

To reduce patch time and cost, we should consider replacing this passthrough with a property test that runs random queries with the same feature flag (force multiplanning). It would repeat the queries that are generated.
