Fix Portraits.xml reloading in unintended scenarios

[SnipUndercover]

Introduced by #890, portraits are reloaded on any scene change. This causes the portraits to reload in unintended scenarios, like reloading the map via F5, opening the Debug Map, or hitting any of the hardcoded F1-F3 binds.

This PR fixes this unintended behavior. Tested locally and it works.

Since this is a detail that we all missed in the first pr, and requires a separate fix because it was not found until later, I believe it's worthy to be referenced in some way in the added code, specifically why those scenes should be excluded and for what reason.

My first attempt with just MapEditor (Debug Map) and AssetReloadHelper (F5) apparently didn't work. I checked and the scene seems to also be changed to LevelLoader (hardcoded F1-F3 binds, the softlock prevention, etc) or LevelExit (restart chapter / dying with a golden), and adding those two worked for both me and the person that experienced the issue.
I'll add the comments later today.

I tested the changes on my end, I confirm that before applying the changes, the unexpected reloading of portraits appears in F1-F3 and F5 scenarios, but I couldn't replicate it with the Debug Map.

This PR fixes the unexpected reloading in F1-F3 and F5 scenarios.

Reverted the LevelExit changes.
I kinda wanted to leave them in considering that this seems useful to have public, even though publicizer exists.
