feature: add nginject condition

[coderaiser]

Running code a couple times with:

run.$inject = ["$document", "$http", "$injector"];
export default function run($document, $http, $injector) {
  'ngInject';
}

produces:

run.$inject = ["$document", "$http", "$injector"];
run.$inject = ["$document", "$http", "$injector"];
export default function run($document, $http, $injector) {
  'ngInject';
}
