Issue description

When changing built-in resources the unsaved changes dialog does only show unsaved built-in shaders if there are no unsaved built-in scripts. Even when clicking on Cancel or Don't Save (for the built-in scripts) it does not ask about the shaders in a second dialog. It looks like get_unsaved_status is first called on the script editor and if it returns something it does not continue to the shader editor, maybe the get_unsaved_status functions can be combined now that both plugins use ScriptEditor

Unsaved script and shader ("test" is a script and closing this dialog in any way does not show the shader dialog)

Only unsaved shader

Steps to reproduce

• Create a new project with a built-in shader and script
• Edit both without saving and try to close the scene, now a confirmation dialog only asking to save the script should show
• Save, edit only the shader and try to close the scene, now it correctly shows the unsaved shader in the dialog
