Returning ref from route results in incomplete response

[jameslaneconkling]

Specifically, returning a ref with a path shorter than the route path results in incomplete response. E.g.

const BaseRouter = Router.createClass([{
    route: 'people[{keys}].name',
    get([_, ids]: [string, string[]]) {
      return ids.map((id) => {
        if (/^!/.test(id)) {
          return {
            path: ['people', id],
            value: { $type: 'ref', value: ['vip', id] }
          }
        }

        return {
          path: ['people', id],
          value: 'some name'
        }
      })
    }
  }, {
    route: 'vip[{keys}].name',
    get([_, ids]: [string, string[]]) {
      return ids.map((id) => ({
        path: ['vip', id, 'name'],
        value: 'special person name'
      }))
    }
}])

// GET ?method=get&paths=[["people", "abc", "name"]]
{
    "jsonGraph": {
        "people": {
            "abc": "some name"
        }
    }
}

// GET ?method=get&paths=[["people", "!abc", "name"]]
{
    "jsonGraph": {
        "people": {
            "!abc": {
                "$type": "ref",
                "value": [
                    "vip",
                    "!abc"
                ]
            }
        },
        "vip": {
            "!abc": {
                "name": {
                    "$type": "atom"
                }
            }
        }
    }
}

In the above case, when matching on ['people', ids, 'name'] but returning a ref from ['people', id] to ['vip', id], the router does not follow up with a call for ['vip', id, 'name']. This is a trivial example, but the general use case of being able to say X is actually Y when asking for a property on X is quite useful.
