Follow-up: Bunch of warnings at arena melee fights

[tos1]

Related topic (v8.* but inherited to v9.3):
"Re: Unmotivated practice melee fighters in arenas" by me

Warning-lines displayed at the beginning of melee fight at arenas. They block the normal message for 20 - 30 seconds.
----
SCRIPT WARNING ON OPCODE 505: Invalid Agent ID: 0; LINE NO 6:
At Mission Template mst_arena_melee_fight trigger no: 33 consequences.
At Mission Template mst_arena_melee_fight trigger no: 33 consequences.
At Mission Template mst_arena_melee_fight trigger no: 33 consequences.

As I wrote in the self-reply to the thread above on 2023-12-12, it is too early to set all 40 agent slots before they spawn.

I experimentally removed the try-block and moved the "agent_set_slot" operation just before the "try_end" of the next trigger 34's exit, and there seems to be no problem. This prevents the warning from appearing and allows normal messages to be displayed without delay.

(Please note that this does not correct the "unmotivated fighters" I pointed out in the topic above.)
