Hi,

I am developping a kibana plugin which, at some point, needs to refresh the fields of a specific index pattern.

I'm using the following code:

```
import uiModules from 'ui/modules';
import 'ui/courier';

var app = uiModules.get('app/myApp', ['kibana/courier']);
app.controller('myCtrl', function($scope, courier) {
    let indexPattern = courier.indexPatterns.get('myIndexPattern-*');
    indexPattern.refreshFields();
});

```

But, I'm getting the following error:

```
angular.js:12477 TypeError: FieldFormat is not a constructor
    at IndexedArray.<anonymous> (http://localhost:5601/bundles/myApp.bundle.js?v=8467:71840:15)
    at IndexedArray.memoized [as getDefaultInstance] (http://localhost:5601/bundles/commons.bundle.js?v=8467:8156:28)
    at new IndexPattern (http://localhost:5601/bundles/myApp.bundle.js?v=8467:71386:90)
    at Object.IndexPatternsProvider.self.make (http://localhost:5601/bundles/myApp.bundle.js?v=8467:71072:13)
    at Object.IndexPatternsProvider.self.get (http://localhost:5601/bundles/myApp.bundle.js?v=8467:71068:48)

```

Indeed, when I debug application, I can see that the property `fieldformats` is empty in `_index_patterns.js`. This makes the `fieldFormats.getDefaultInstance()` method fail : At line 79 of `field_formats.js`, the code `let FieldFormat = self.byId[conf.id];` returns `Undefined`.

Do I miss something in order to use indexPatterns in my plugin ?

_I use Kibana 5.x branch_

You probably just need to include the default field formatters:

```auto
import 'ui/stringify/register';

```

You're right, it works with this import.

Thank you.
