Neeraj/v20.03 pagination uid

[antblood]

Pagination param "after" does not work when using func: uid(v)

for query

{
  var(func: has(name@en), first: 50) {
    test as uid
  }

  ss(func: uid(test), first: 2, after: 0x6) {
    uid
  }
}

the response was

{
  "data": {
    "ss": [
      {
        "uid": "0x4"
      },
      {
        "uid": "0x6"
      }
    ]
  }
}

I don't understand the code but it's a cherry-pick so LGTM
