mod_storage_internal: Fix fast trimming of archive with exactly one item
This method would previously never delete the first (and only) item
since it works out which item should become the first item after the
trim operation, which doesn't make sense when all should be removed.
This also works as an optimization for when all the last item should be
trimmed, thus items should be removed.
