[Javascript] Improve Chrome console output by explicit constructor name instead of "exports"

Description

When outputting responses from the generated Api, Chrome is smart enough to provide smart type names for the objects that are rendered. For example, when calling a api function in console, Chrome gives me:

api.getSomething().then(function() { console.log(arguments); })
> [exports]

This is because of the generated Models having the following code:

var exports = function() { 
    var _this = this;
}
...
return exports;

To be honest, even I am not too sure how Chrome does this in V8, as Firefox definitely does not do this for me. Edit: seems like Chrome may be simply using obj.constructor.name as the output.

api.getSomething().then(function() { console.log(arguments[0]); })
> Object { ... }

Anyway, just a suggestion, not a big one =)

Even a quick hack like this works, for example in a model file called ResourceModel.js:

  var ResourceModel = function() {
    var _this = this;
  };

  var exports = ResourceModel;
  ... 
  return exports;

api.getSomething().then(function() { console.log(arguments); })
> [ResourceModel]
