[Emmanuele Bassi <ebassi src gnome org>]

    Improve filters for stable/unstable/oldstable tags
    
    We should use proper filters instead of simply getting the
    first element in the array.
    
    Additionally, for unstable tags we should conditionally show
    the whole block, in case we haven't branched yet.
