When sub views are created using the Nested Views Plugins, these sub views cannot be selected when assigning Job Priorities to JobGroups.

To reproduce:

1. Install Priority Sorter and the Nested View Plugin
2. Create a new View and choose the "Nested View" type
3. Create a couple of sub views in this Nested View
4. Go to http://jenkins:8080/advanced-build-queue/ and Add a Job Group

What is expected

• All normal Views and all Nested Views and all views in the Nested Views are listed

Actual outcome

• Only the normal Views and the Nested Views are show. The sub views are not shown
