Don't try to update the visual shader graph if it doesn't exist yet

Browse Source 
When setting shader mode on a visual shader that was just created in the
editor we try to _update_graph(). However, the graph does not yet exist
in the visualshadereditor. This gets populated in
VisualShaderEditor::edit() which hasn't been called yet.

This PR simply changes the logic to not try to update the non-existent
graph.
