pass currentPath to persist through hot code reload

I was having trouble with the current route not persisting through a hot code reload.  I came up with a quick solution that seems to fix the problem.  Is this the right way to go about it?

In `phonegapapp.js`, accept a `currentPath` parameter and pass to `MeteorRider.init()`:

``` javascript
phonegapapp = {
  ...
  meteorRider: function(currentPath) {
    currentPath = typeof currentPath !== 'undefined' ? currentPath : '';
    MeteorRider.init(currentPath);
  }
}
```

Receive `currentPath` within `meteor-rider.js` and use in `window.history.replaceState()`:

``` javascript
var MeteorRider = {
  init: function(currentPath) {
    ...
    // trigger request
    $.ajax({
      ...
      success: function( data, textStatus, jqXHR ) {
        ...
        window.history.replaceState({}, "", meteorUrl + currentPath);
      }
    });
  }
}
```

And then, in the `Meteor.startup()` function, simply pass the current route (I'm using Iron-Router):

``` javascript
if(typeof phonegapapp !== 'undefined'){
  Meteor._reload.onMigrate('phonegapapp', function(){
    phonegapapp.meteorRider(Router.current().path);
    return [false];
  });
};
```
