    loader: Do not raise error when reloading a repo not fully ingested
    
    When a subversion repository did not get fully ingested during a first
    load (an error occurred when processing a revision that stopped the
    loading), trying to reloading it again will raise a ValueError instead
    of generating the same snapshot as the previous visit.
    
    So ensure to initialize the _snapshot and _last_revision class member
    of the loader to the latest loaded snapshot and revision if they exist
    to avoid raising an error and generate an uneventful visit.
