Calling setParameter on the mongos does not forward the parameter to shards. Since shouldMultiDocTxnCreateCollectionAndIndexes is referenced in code that doesn't execute on mongos for the implicit collection case, it needs to be set on the shard individually. Thanks esha.maharishi for your assistance in investigating this.

I've updated the title of this ticket to add a regression test that setting FCV to 4.2 disables the feature.
