I think you are correct.  That subtest should generate two query objects
and use a separate object for each of the two glBeginQuery calls.

It sounds like we also need a subtest for a glBeginQuery / glEndQuery
followed by a glBeginQuery with the same id but a different target.

Can you provide patches for those?
