arb_vertex_array_object: Add test for deleting object zero

As of commit 781a78914c7, this test fails with:

arb_vertex_array-delete-object-0: src/mesa/main/hash.c:240: _mesa_HashRemove_unlocked: Assertion `key' failed.
Aborted (core dumped)

Marek already has a patch on the Mesa list for this issue.
