[TECHNICAL-SUPPORT] LPS-40754 Global private asset category assignment can be removed unintentionally

Hi Julio,

before this fix, a user who didn't have permission to view a category could remove it unintentionally.
We checked how the Asset Publisher configuration works, and saw that the categories are stored in the portlet preferences, so if a user can configure the Asset Publisher, he will be able to see the categories without view permission.
I don't think that we should follow this, so Giros created a solution which preserves the categories even if the user can't see them.

Could you please review the changes?

Thanks,
Tamás
