Striders and pigs walk faster if you unmount them while boosted

I used the boost ability on a strider, but when I unmounted it, it started to run around faster than usual.

Steps to Reproduce:

1. Spawn a strider
2. Equip a saddle on the strider
3. Mount the strider
4. Use a warped fungus on a stick to boost the strider
5. Unmount the strider
6. Hit the strider or wait for it to start moving on its own

Observed Results:
The strider moves very fast.

Expected Results:
The strider should move at normal speed.
