Warden AI doesn't function properly when it rides on entities

Warden AI doesn't function properly when it rides on entities.

This results in the following situation:

1. Can't use close range attacks.
2. Can't use sonic boom attacks.
3. Won't play the roar animations.
4. Won't play the sniffing animations.
5. If the riding entity is a mob, warden can't control it.

Below is the command to reproduce:

/summon minecraft:boat ~ ~ ~ {Passengers:[{id:"warden"}]}

/summon minecraft:minecart ~ ~ ~ {Passengers:[{id:"warden"}]}

/summon minecraft:pig ~ ~ ~ {Passengers:[{id:"warden"}]}
