refineShardKey should verify indexes on shards with chunks

const dbName = "test" ; const collName = "foo" ; const ns = dbName + "." + collName; let testDB = st.s.getDB(dbName); let testColl = testDB.foo;   // Create a sharded collection with one chunk on shard0. assert.commandWorked(st.s.adminCommand({enableSharding: dbName})); assert.commandWorked(st.s.adminCommand({movePrimary: dbName, to: st.shard0.shardName})); assert.commandWorked(st.s.adminCommand({shardCollection: ns, key: {x: 1}}));   // After this there's only a chunk on shard 1 assert.commandWorked(st.s.adminCommand({moveChunk: ns, find: {x: 1}, to: st.shard1.shardName}));   // So this only creates an index on shard 1 assert.commandWorked(st.s.getCollection(ns).createIndex({x: 1, y: 1}));   // But this fails with "InvalidOptions: Please create an index that starts with the proposed shard key before sharding the collection" because it checks indexes on the primary shard (shard 0) assert.commandWorked(st.s.adminCommand({refineCollectionShardKey: ns, key: {x: 1, y: 1}}));
