A mooshroom sheared into a cow while a warden is angry at it will stop being targeted by the warden

The bug

If a warden gets angry at a mooshroom, and said mooshroon transforms into a cowbefore the warden can kill it, the warden will not remain angry at this cow and will need to become aggressive toward it a second time.

How to reproduce

1. Summon a mooshroom
2. Summon a warden nearby
3. Have the warden get angry at the mooshroom
4. Shear the mooshroom before the warden can kill it

Expected results

The warden would remain angry even when the targeted mooshroom becomes a cow.

Actual results

It loses its target.
