    list_view: Fix key events regression
    
    Since f692a93d, the left/right keys do not expand/collapse trees.
    Also, the [Spacebar] key opens the file instead of previewing it.
    
    This is because we return earlier when we get a state field. This
    is a typo, because it should be the reverse.
    
    But actually, it is safe to assume it is always TRUE, because at this
    point we got a keval field already. So, skip the condition checking.
