Describe the problem

When I disable the auto-save, then enable it in a temp sketch, then the native save as file dialog pops. I think it should not.

A temp sketch is a sketch that is not saved to directories#user location.

To reproduce

• Open a new sketch but do not touch it!
• Open settings and make sure auto-save is disabled.
• Enter one space to the end of the file.
• Open settings and enable auto-save.
• Hit OK.
• Native file dialog pops.

Expected behavior

It should not. IDE2 should know it's a temp sketch and should not prompt the save as dialog.

Problem: by default, Theia saves the editor when this setting/preference is changed, and the new auto-save value "is enabled".
