Comments in rendering code not retained after transformation of ReactNative JSX (T7193)

> Issue originally made by @mishaaq
### Bug information
- **Babel version:** 6.7.2
- **Node version:** 5.4.0
- **npm version:** 3.3.12
### Options

```
presets: react-native
comments: true
compact: false
retailLines: false
```
### Input code

```
class SimpleComponent extends Component {

render() {
var selected = 1;

/* comment 1 */

return (
/* comment 2 */

test {/* comment 3 */}
{/*
comment 4
*/}

)
}
}
```
### Description

The output is:

```
var SimpleComponent = function (_Component) {
_inherits(SimpleComponent, _Component);

function SimpleComponent() {
_classCallCheck(this, SimpleComponent);

return _possibleConstructorReturn(this, Object.getPrototypeOf(SimpleComponent).apply(this, arguments));
}

_createClass(SimpleComponent, [{
key: "render",
value: function render() {
var selected = 1;

/* comment 1 */

return React.createElement(
View,
null,
React.createElement(
Text,
null,
"test "
)
);
}
}]);

return SimpleComponent;
}(Component);
```

As you see - only "comment1" is retained. All the comments enclosed by return statement are missing.

Start by reproducing the supplied JSX with Babel 6.7.2, the react-native preset, and comments enabled, then trace the JSX transformation that produces React.createElement calls. Done means comments 2–4 are retained in the generated output while comment 1 remains intact.
