No way to refresh panini cache [v2.0]

When I use watch to update files I have the next workaround:

```
import paniniG from 'panini/gulp';

const panini = paniniG.create;
...
panini('src')...
```

In this case partials updated between watch cycles.
The problem is that `locales` data is not updated.

If I use regular way without `.create` then it's vice versa: locales data updated, but partials are not.
