CPU Virtual tests removed, since the scheduler between CPU/GPU is the same

[jjfumero]

Description

The CPU Virtual Tests were failing due to the thread -scheduler changes. Since the CPU scheduler now uses the Generic GPU scheduler, there is no distinction between them in regards with the Virtual Tests. This PR fixes this.

Problem description

Virtual Tests for CPU giving wrong results because the scheduler used is the Generic GPU scheduler.
