object_resolve_path*() ambiguous path detection breaks when
ambiguous==NULL and the object tree have 3 objects of the same type and
only 2 of them are under the same parent. e.g.:
/container/obj1 (TYPE_FOO)
/container/obj2 (TYPE_FOO)
/obj2 (TYPE_FOO)
With the above tree, object_resolve_path_type("", TYPE_FOO, NULL) will
incorrectly return /obj2, because the search inside "/container" will
return NULL, and the match at "/obj2" won't be detected as ambiguous.
Fix that by always calling object_resolve_partial_path() with a non-NULL
ambiguous parameter.
Test case included.
