Holy Persuasion uses the old Test of Faith Teleport animation for Holy Persuasion, regardless of whether you convert an enemy or teleport an ally.

It should use both animations.

1. When converting (when cast on an enemy creep), it should use cast4_holypersuasion (ACT_DOTA_CAST_ABILITY_5)
2. When teleporting (when cast on an ally or own unit), it should use cast3_testoffaith (ACT_DOTA_CAST_ABILITY_3)
