[PATCH 28/28] repack_without_ref(): call clear_packed_ref_cache()

From: Michael Haggerty <mhagger@alum.mit.edu>

Call clear_packed_ref_cache() from repack_without_ref(). This is a more logical place to call it than from delete_ref(). Also, repack_without_ref() is smart enough to know that it doesn't have to invalidate the cache if the reference was not found among the packed refs.
