fix(simple_auth_flutter_example): parameter order

[CoreyCole]

I believe the azureAdTestApi.dart example is wrong/out-of-date. It orders the params:

"AzureAdTestApi","resource","client_id","redirecturl"

When it should be (defined here):

name, this.clientId, this.resource, this.redirectUrl

Kind of an aside, but what is the design thinking behind only some of the parameters being named? Naming all the parameters would have made this error more obvious:

@AzureADApiDeclaration(
  name: "AzureAdTestApi",
  clientId: "resource",
  resource: "client_id",
  redirectUrl: "redirecturl",
  azureTennant: "azureTennant",
  clientSecret: "client_secret"
)
abstract class AzureADDefinition {

}

The error is easier to see

clientId: "resource",
resource: "client_id",

Thanks!
