      The createIndex command wasn't checking if featureFlagCollModIndexUnique was enabled when indexOptions included prepareUnique. We previously relied on an inner layer feature flag check, but SERVER-87373 had to remove that check as it was causing invariant failures and crashing the server. We should have createIndex command to check for featureFlagCollModIndexUnique at the entry point, similar to how collMod does.
