conditions on enchantments applied to creatures silently fail with no message

[Standing-Storm]

Describe the bug

Testing #78586 and the modifications to the slowing spells I applied did nothing. Further testing showed that enchants applied to monsters always evaluate conditions to false, even something that should always be true like 1 == 1 or u_is_monster

Attach save file

N/A, requires modification (at the moment)

Steps to reproduce

1. Put the following JSON in your game somewhere so it loads:

{
"type": "effect_type",
"id": "effect_frozen_monster",
"name": [ "Super Slow" ],
"desc": [ "This monster is unbelievably slow!" ],
"show_in_info": true,
"enchantments": [
{
"condition": "u_is_monster",
"values": [
{
"value": "SPEED",
"add": -1000
}
]
}
]
}

2. Using the debug menu, apply this effect to a monster
3. Monster's speed is not reduced.

Expected behavior

Ideally, conditions work. In the meantime, an error message to appear.

	// Dialogue conditions for monsters seems like overkill.
	// Definitely not an excuse for not knowing how to add them. Nope! Sure isn't!
