RBAC user upsert returns "malformed or role parameters are undefined: [cluster_admin[default]]"

with core 1.4.7-SNAPSHOT(from commit 14d06355fc84a343bbc5cdf47ffdc6fd20c0fcd3), java client 2.4.7-SNAPSHOT (from commit aab50ea8f9674a4681443101d5da7f9b8c9c7770), and server build 5.0.0- 3217

CouchbaseCluster cluster = CouchbaseCluster.create(env, nodes);

cluster.authenticate("Administrator", "password");

        cluster.clusterManager().upsertUser("sdkqecertuser", UserSettings.build().password("password").roles(

                Arrays.asList(new UserRole("admin", "default"))

        ));

INVALID_ARGUMENTS, msg: "Cannot assign roles to user because the following roles are unknown, malformed or role parameters are undefined: [cluster_admin[default]]"

Test against 5.0.0-3203 works as expected
