[gtksourceview] SearchContext: remove dispose_has_run() function

    SearchContext: remove dispose_has_run() function
    
    It was true when the SearchContext had a strong reference to the buffer.
    The buffer was NULL only if dispose_had_run(). But it is now a weak
    reference. So the buffer can be NULL even if dispose() hasn't run.
    
    Doing manually the check for buffer == NULL can be done easily, so a
    function is not really needed.
