    CompletionItem: emit the ::changed signal also in set_text()
    
    It was not emitted because the other GtkSourceCompletion* classes don't
    need to update the UI when the text changes (the text is read only when
    activating the proposal).
    
    But external code might have a different implementation that needs to
    update the UI when the text changes, for example if the text is shown in
    the GtkTextBuffer in gray, see:
