Named queries without variables don't parse

[campoy]

What version of Dgraph are you using?

v1.1.0

Have you tried reproducing the issue with the latest release?

yes

What is the hardware spec (RAM, OS)?

playground

Steps to reproduce the issue (command/config used to run Dgraph).

Running this query works:

query works($name: string = "Francesc") {
  q(func: has(name)) {
    name
  }
}

But if you realize that the query doesn't use the variable and you decide to remove it:

query works() {
  q(func: has(name)) {
    name
  }
}

You get the error:

Error Name: t

Message: line 1 column 12: Invalid comma in var block

URL: http://localhost:8080/query

Expected behaviour and actual result.

It should just parse it correctly
