[gnome-software] Use 1 as a minimum cache age when doing user initiated refresh

[Kalev Lember <klember src gnome org>]

    Use 1 as a minimum cache age when doing user initiated refresh
    
    It turns packagekit treats cache age of 0 as "unset", and changes it to
    G_MAXUINT ("never refresh") before passing it to backends. Fix this by
    just using 1 instead of 0 to force a minimum cache age.
