    st: Be more forgiving when calling get_theme_node() on unstaged widgets
    
    While it is obviously still an error to call get_theme_node() on a
    widget that hasn't been added to the stage hierarchy yet, asserting
    on it hasn't proven too successful in avoiding those errors - it's
    likely the most frequent reason for crash reports. Just accept that
    there'll always be code paths where we can hit this case and make
    it non-fatal.
