Don't create image/file virtual fields for category items, while in Admin Console

In-Portal uses virtual fields to map data from multiple database tables into a single virtual database record.

That fields could also be used to create various Front-end controls. In particular such functionality is used to create image/file upload controls on link suggest/modify forms.

Additional database are used to solve that particular task. However no such controls are used in Administrative Console, but these database queries are still performed.

I propose to skip that database queries, while in Admin Console.
