Looks like we could solve this bug just by making
tree-widget-image-enable default to t unconditionally then.  It seems to
do the right thing in that case, e.g., I tried

    ;; from 
https://stackoverflow.com/questions/25104291/change-text-of-tree-widget-node
    (widget-create
     'tree-widget :open t :tag "one"
     :args
     (list (widget-convert
            'tree-widget
            :tag "two"
            :args (mapcar (apply-partially #'widget-convert 'item)
                          '("three" "four")))))

it shows image when looking at it in a graphic frame, and text when
looking at the same buffer in a tty frame.
