[recipes] Tweak the handling of the done button

[Matthias Clasen <matthiasc src gnome org>]

commit 2531af959d957c4db1cbad13e7713c65c204da68

    Tweak the handling of the done button
    
    Only show the done button on the last step of cooking mode
    if there are no running timers. This is not quite perfect,
    since we may show and then hide the button if there's a timer
    on the last step that gets started, but it is still an
    improvement.
