lookupInAnyReplica raising DocumentUnretrievableException when it shouldn't

This code:

String docId = UUID.randomUUID().toString();

collection.upsert(docId, JsonObject.create());

LookupInReplicaResult result = collection

  .lookupInAnyReplica(docId, CbCollections.listOf(get("bad..path"))); 

Results in a DocumentUnretrievableException being raised when AFAICT it shouldn't.

(This was another one caught by FIT, so thank you again Matthew Bray )

As part of fixing, please re-enable the tests I've temporarily @IgnoreWhen-ed in FIT in https://review.couchbase.org/c/transactions-fit-performer/+/195104.
