* [Refactor] Removes redundant else structures

This one has a bit more refactoring going on, so you will need a good test run n this. Or drop it, if you don't think it is worth it :)

It would clean stuff up a bit to extract a large part of the code in the for loop to a separate getItem method.
That way you can do early returns more easily and only need one result.push(item);

Something like:
``` 
                item = this.getItem(propPrefix, decl);
                result.push(item);
```
