[Fixed at v9.4] Melee (crowd) fight at arena ends at about 20 fighters left

[tos1]

The number of remaining fighters is displayed as 40, the same as in v8.*, but the match ends even though there are still about 20 remaining (and the master of the tournaments gives 750 stags).

(Sometimes the remaining number is displayed as 20, sometimes as 19, etc.)

In addition, all problems derived from v8.* seem not to be fixed at v9.0:
- Waiting in a line without doing anything.
- Just look at each other without doing anything.
- There are cases where the remaining number becomes -1 or -2 when everyone is defeated.
- Many OPCODE warnings in the [Q] - [messages] window (and that prevents normal messages from starting to display for several tens of seconds).

- How to reproduce it/when/why it happens:
Visit a arena of a town, start melee (crowd) fight, beat about 20 person but always check the number of left fighters if it get closer to 20.

(v8.2 doesn't have the "20 left" problem)

Follow-up.
After doing hand-disassembly of v9.3, I've just found the cause.
In the mst_arena_melee_fight, "$g_arena_training_num_agents_spawned" is increased twice in total at trigger 34 and 37 (counted from 0) per spawning.

I don't know if it's okay to simply delete one or the other, but after I experimentally deleted the latter, the number of remaining fighters returned to normal (finishing at about 40).

(Among the other issues above, I have also made progress on the WARNING, so I will write a follow-up on another topic.)

(v8.2 doesn't have the problem)

Done some fixes for this - will need proper testing in 9.4. Thanks!
