Fix finalize of WeakRef
* gc.c (wmap_final_func): remove WeakRef object reference from the
array.
* gc.c (wmap_finalize): remove recycled object references from weak
map hash properly. How to get object reference from object id was
wrong. st_delete() doesn't work properly if key and value arguments
are same. The key of obj2wmap is referenced object and the value of
obj2wmap is WeakRef array.
* gc.c (wmap_aset): obj2wmap should contain WeakRef array in the
definition.
* test/test_weakref.rb
(TestWeakRef#test_not_reference_different_object): add a test for
above.
