    Fix iterating hash table in jaw_impl_finalize
    
    236b9dda9b44 ('JNI: fix crash on java applications') turned
    jaw_impl_finalize's iter into a pointer, passed as such to
    g_hash_table_iter_init. But that is not how that API works, the original
    code was correct. This restores the original correct behavoir,
    avoiding warnings on jaw_obj finalizations.
    
    Fixes https://bugzilla.gnome.org/show_bug.cgi?id=793620
