Fix Trapper Information gain as it "should be"

[Peybro]

The way it is now:

The trapper gets his information about the players from the traps at the time the meeting starts (or when the chat is available).

The problem with this is that if a player in the trap gets a sidekick, the trapper will magically see the sidekick in the meeting and not the player's role when they were in the trap.

What the PR changes:

Since the trapper receives their information via the trap, they should not notice any subsequent changes. With the PR, the trapper receives the role information about the player at the time in the trap.
