Title: Added $admin->setRequest($request) lines to HelperController

Prevents "The Request object has not been set" errors.

I stumbled upon this error when using "sonata_type_model_list", because after selecting an object, an ajax request is made to "admin/core/get-short-object-description", which resolves to "getShortObjectDescriptionAction()".
However, I added the "setRequest" line to the other functions in the HelperController as well.
