DrawManager: Fixed memory leak in test cases

Memory leak is introduced as test cases reinitializes the GPU stack.
Added a call to GPU_backend_exit to fix this.

In GPU_backend_exit the GPU backend was destroyed but the pointer wasn't
reset for reuse. This patch also clears the pointer to be reused.
