[PATCH] diff-lib: clear `pending` object-array in `index_differs_from()`

Instead of conditionally freeing `rev.pending.objects`, just call `object_array_clear()` on `rev.pending`. This means we don't poke as much into the implementation, which is already a good thing, but also that we free the individual entries as well, thereby fixing a memory-leak.
