Series test_objagg: Fix objagg and hints refcount leak when create objagg2 failed | expand

The reference couting issue happens in one exception handling path of
test_hints_case(). When failing to create objagg2, the function forgets
to decrease the refcount of both objagg and hints, causing a refcount leak.

Fix this issue by jumping to the label "err_check_expect_hints_stats".
