Ensure there is a committed ray intersection before calling rayQueryGetIntersectionInstanceIdEXT(..., true)

The test uses rayQueryGetIntersectionInstanceIdEXT(, true) (what corresponds
to OpRayQueryGetIntersectionInstanceIdKHR with Intersection ==OpRayQueryCommittedTypeKHR)
without actually checking if there is any committed intersection.

The  SPV_KHR_ray_query spec requires that there should be a current committed intersection:

"""
Intersection is RayQueryCommittedIntersectionKHR, there must be a current committed intersection
(see OpRayQueryCommittedTypeKHR).
"""

This change fixes that by sorrounding the rayQueryGetIntersectionInstanceIdEXT call with
the check if the curent intersection is not 'None'
