Bug resolved in displaying resources in particular group

* As the bug reported that, in all groups , "home" group files were also visible .
* It was because while making a query especially for "files & pandora videos" there were no group_set value included , which states that resource belongs to particular group. Hence all pandora videos were visible in all the groups in nroer instance. 

* It was only on nroer instance because only that instance contains the pandora videos for home group.
* Bug resolved now, as i have included group_set value for querying "files & pandora videos"
