Calixte Denizet 06f72d5662 [Editor] Don't try to use an non-existing canvas when rendering an invisible existing stamp editor
It fixes #19239.

When the canvas isn't existing the editor has no image: it's fine because the editor is invisible.
Once it's made visible, the canvas is set when the annotation layer has been rendered.
