Classification store groups sorter fix

What was the issue? 

When creating new classification store collections and adding groups to collections, there is an option to define a sorter for every group inside the collection. That sorter option wasn’t initially applied when a new classification store collection was added to the object.

How did you solve it? 

I passed that sorter to Javascript and applied it when a new classification store collection is added to the object.

Why is this fix important?

This is important because it fixes a bug and now Pimcore users will have a better experience when using classification stores.
