    swipe-tracker: Remove check in _new()
    
    Don't check if the swipeable already has a swipe tracker. This check will
    become redundant in the next commit with hdy_swipeable_get_swipe_tracker(),
    as a swipeable must always have a swipe tracker now, and causes problems
    for HdyStackableBox, as we create the swipe tracker during the mixin
    creation, and so can't route hdy_swipeable_get_swipe_tracker() through the
    mixin yet.
