Legacy Durability options set to incorrect C++ enumerations

When building the legacy durability options for KV, subdoc and binary operations, the persist_to and replicate_to options are swapped. See snippet below. This needs to be corrected.

couchbase::replicate_to replicate_to{ couchbase::persist_to::none };

couchbase::persist_to persist_to{ couchbase::replicate_to::none };
