Disable SerializationFeature.FAIL_ON_EMPTY_BEANS in dataMapper

[PetrHeinz]

Avoids errors when objects without serializable properties is logged, eg.:

Error processing JSON data : No serializer found for class org.postgresql.core.v3.replication.V3ReplicationProtocol and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationFeature.FAIL_ON_EMPTY_BEANS) (through reference chain: java.util.ArrayList[1]->java.util.HashMap["args"]->org.postgresql.jdbc.PgConnection[1]->org.postgresql.jdbc.PgConnection["QueryExecutor"]->org.postgresql.core.v3.QueryExecutorImpl["ReplicationProtocol"])

Disabling it seems like a reasonable default in our case (better than dropping logs).

Tested with by logging a dummy object: logger.info("Logging empty beans.", new NoPropertiesBean());

    // A class with no properties that Jackson can serialize.
    // It doesn't have public fields, nor does it have any getter methods.
    private static class NoPropertiesBean {
        private int id; // Private field without a getter method.

        public NoPropertiesBean() {
            this.id = 1; // The constructor sets the value, but it's not accessible for Jackson.
        }
    }

Gets logged as an empty object {}:
