Application fails to bootstrap with two levels of dynamic params

[ggoodman]

When both a parent and child state define optional, dynamic parameters, the application fails to bootstrap.

  $stateProvider.state("parent", {
    url: "/?parentParam",
    templateUrl: "parent.html",
    params: {
      parentParam: {
        value: null,
        dynamic: true
      }
    },
    controller: function () {

    }
  });


  $stateProvider.state("parent.child", {
    url: "/child?childParam",
    templateUrl: "child.html",
    params: {
      childParam: {
        value: null,
        dynamic: true
      }
    },
    controller: function () {

    }
  });

Results in the following error:

Uncaught Error: [$injector:modulerr] Failed to instantiate module plunker due to:
Error: Missing required parameter 'parentParam' in state 'parent.child'

I'm wondering if this is actually just a more complicated example of #1073. They both present with the same error message, but #1073 is perhaps a more general case.
