Space: post move from munges paths

Update post_move_from_storage_service to pass the same paths into it as
move_from_storage_service.  Because some path munging is done now,
handle if one or both of the paths passed are None.
Space: Move deleted staging copy to post-move function

Move deleting the staging copy to after the protocol specific post
move has run, in case it is needed by the child space. Delete stubbed
functions that were going to do this.
Package: Update Package status correctly when storing

FS.
