function NodeQueryAlterTest::testNodeQueryAlterOverride

Tests 'node_access' query alter override.

Verifies that node_access_view_all_nodes() is called from node_query_node_access_alter(). We do this by checking that a user who normally would not have view privileges is able to view the nodes when we add a record to {node_access} paired with a corresponding privilege in hook_node_grants().
