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

["Martin Ågren" <martin.agren@gmail.com>]

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.
