Test / Fix Imp mode

[atlesque]

There might be a few issues with the Imp mode, especially when tracking your own color is enabled. Test this once more and see if any bugs arise.

There was one bug / question reported by Triple A (AAA) but I couldn't verify what they meant:

If you are the impostor, when you check the colors of your buddies, why does their icon go to the hitlist and the suspect page?

Found two issues:

Regarding Triple A's issue:

1. Start a game with multiple imposters, with yourself being one of the imposters
2. Enable Imposter mode
3. Check the Imp? checkbox for the other imposters
4. They are automatically moved to your Hitlist, and they are suspected by you

Here, when Imposter mode is enabled, your fellow imposters should either be moved to the My protectors column, or not moved at all. They should never go to the Hitlist.

The other issue is when you have Track player color enabled and you are an imposter. When moving your own color from the Death column back to Unknown, you lose your imposter status and Imposter mode gets disabled.
