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.
