getResource changes value of strings with quotes

`FormState.js` contains the function:

```
this.getResource = function () {
return JSON.parse(JSON.stringify(_this.obj).replace(/"\s+|\s+"/g, '"'));
};
```

The regex replace can change the value of a form element. For example, if you have a `textarea` with the value `foo "bar" foo` the regex will change it (remove last space) to `foo "bar"foo` which is not the desired string.
