Steps to reproduce:
1. Open the attached project
2. Open the scene 'Scene 1'
3. Build 'Scene 1' and check the console

Console log: Name: '0', Path: Temp/__Backupscenes/0.backup

4. Create a new scene 'File/New Scene'
5. Step 3

Console log: Name: 'Scene 1', Path: Assets/Scene 1.unity

Expected: PostProcessScene callback should return proper scene info on build, regardless of the scene opened
Actual: PostProcessScene callback returns temporary file info when building a scene that's currently open
