"Save As" fails when attempting to replace existing sketch

[per1234]

Describe the problem

When an existing sketch file is selected during a "Save as.." operation, the IDE asks the user to confirm the overwrite, but does not overwrite regardless of the user's choice.

To reproduce

1. Select File > New from the Arduino IDE menus.

2. Select File > Save as... from the Arduino IDE menus.

3. Save the sketch to a convenient location.
   I'll refer to this sketch as "Sketch1", but the name doesn't matter.

4. Select File > New from the Arduino IDE menus.

5. Modify the text in the sketch file so it's different from the "Sketch1" sketch.

6. Select File > Save as... from the Arduino IDE menus.

7. Open the folder containing "Sketch1".

8. Click on Sketch1.ino

9. Click the "Save" button.
   A dialog opens:

   Confirm Save As

   Sketch1.ino already exists.
   Do you want to replace it?

   

10. Click the Yes button, indicating you want to replace Sketch1.ino.

11. Open Sketch1.ino in a text editor.

🐛 Sketch1.ino contains the original text it was first saved with.

Expected behavior

When I confirm I want to overwrite the sketch, it should be overwritten.

Additional context

This also occurs when doing a "Save As..." with "Sketch1". But that requires having "Auto Save" disabled and risks being mistaken for #65.

For this reason, I chose to use two sketches in the demo, which works regardless of the "Auto Save" setting.

This works as expected when using Arduino IDE 1.x.

I also tested this with the build from #211 with the same results I described above.
