Describe the bug
The saved versoin of the sketch is always compiled, even when there are unsaved changes in the editor.

To Reproduce
Steps to reproduce the behavior:

1. File > Preferences
2. Uncheck the box next to "Auto save".
3. Click the "OK" button.
4. Open a sketch that will compile without errors (e.g., File > New).
5. Make changes to the sketch code that would cause a compilation failure. Don't save.
6. Sketch > Verify/Compile. The compilation passes.

Expected behavior
The sketch code in the editor should be compiled, as is done in the Arduino IDE.
