plumbing: format/packfile, fix panic retrieving object hash.
In some cases the original data is not saved before it is cleaned and forces a panic when it's needed. The change adds ObjectToPack.CleanOriginal to be used to clean original object instead of: object.Original = nil Now when the Original data is freed because it's no longer in the pack window a SetOriginal call is done to make sure that Size, Hash and Size data is not lost.
