A villager that converts to a witch while the warden is angry at it will stop being targeted by the warden

The bug

If a warden gets angry at a villager, and said villager transforms into a witch before the warden can kill it, the warden will not remain angry at this witch and will need to become aggressive toward it a second time.

How to reproduce

1. Summon a villager
2. Summon a warden nearby
3. Have the warden get angry at the villager
4. After the warden roars, run the command

   /execute at @e[type=villager] run summon minecraft:lightning_bolt ~ ~ ~

Expected results

The warden would remain angry even when the targeted villager becomes a witch.

Actual results

It loses its target.
