Uncaught error - when ACL feature is turned on, and login credentials not passed

[prashant-shahi]

When I ran the example script against dgraph cluster with ACL feature turned on, I encountered the following error, which wasn't of much help.

ERROR:  TypeError: Cannot read property 'serializeBinary' of undefined
    at Object.createPayload (/Users/prashant/dgraph-code/dgraph-js/examples/v1.1/node_modules/dgraph-js/lib/types.js:65:105)

Meanwhile, we need to have more tests around ACL as well.

Even when the Dgraph cluster is not properly up and running, or invalid gRPC address is used, the same issue was encountered.

Turns out this issue also happens when an invalid schema is passed.

It will be resolved with the release of v2.0.2.
