fix(1.x/componentLoaderProvider): make provider methods chainable

This commit allows us to chain `componentLoaderProvider` methods like this:

```js
app.config(function (componentLoaderProvider) {
  componentLoaderProvider
    .setCtrlNameMapping(function (name) {
      // ...
    })
    .setTemplateMapping(function (name) {
      // ...
    });
});
```
