Data writer should be able to read but not able to

With 5.0.0-3516 (RC5), Java SDK 2.5.0, data writer can not read.

According to spec, data writer should have read permission as well.

Steps:

1. Create 'default' bucket
2. Create 'datawriter' with 'password' and associate 'default' bucket
3. Run following code

public class RbacTest {

public static void main(String[] args) {

// Initialize the Connection
Cluster cluster = CouchbaseCluster.create("172.23.123.244");
cluster.authenticate("datawriter", "password");
Bucket bucket = cluster.openBucket("default");

// Create a JSON Document
JsonObject arthur = JsonObject.create()
.put("name", "Arthur")
.put("email", "kingarthur@couchbase.com")
.put("interests", JsonArray.from("Holy Grail", "African Swallows"));

// Store the Document
bucket.upsert(JsonDocument.create("u:king_arthur", arthur));

// Load the Document and print it
// Prints Content and Metadata of the stored Document
System.out.println(bucket.get("u:king_arthur"));
}
}

Expected : no error

Actual : Exception in thread "main" com.couchbase.client.core.CouchbaseException: ACCESS_ERROR (Context: Authorization failure: can't execute GET operation without the Read privilege, Reference: a5664208-84cc-4974-13c0-468e8e455fd0)
