Llamas don't leave their caravan when being leashed by a player

When a player attaches a lead to a llama that is part of a caravan, and tries to lead that llama somewhere else, that llama won't leave the caravan.

To reproduce

Using MC-205200:

1. Leash a llama onto a fence

2. Spawn a llama next to it

3. Leash that llama

4. Walk away from the fence
   → ❌ The llama will try to get back to the fence, and at some point the lead will pop off

With multiple llamas:

1. Spawn multiple llamas

2. Attach a lead to one of them

3. Walk a bit
   → The llamas form a caravan

4. Attach a lead to the last llama in the caravan

5. Walk a bit
   → ❌ The last llama walks backwards and tries to follow the second-to-last llama in the first caravan
