SaveScene is triggered on starting play mode even if the scene is not dirtied
To reproduce:
1. Open attached project
2. Open Project Settings, select "Editor" and enable "Enter Play Mode Options (Experimental)" setting. Keep "Reload Domain" and "Reload Scene" unticked.
3. Open Scene "Transform_30000"
4. Play and stop the scene a few times
Actual: SaveScene is called on each start of the play mode, no matter the state of the scene
Expected: On second and further launches, as the scene was not dirtied, it shouldn't spend time on saving a backup again

Resolution Note:
The scene file is saved along with instanceID remapping information which is needed when reloading the scene when exiting Play mode. Closing it as a bug and moving it to our internal optimization backlog as we want to tacle this optimization as part of a larger refactoring. We will be using this bug reports test setup when picking up the task.
