[MC-122308] Zombies can no longer break wooden doors

The bug

It appears zombies can no longer break wooden doors. This used to work in 17w46a.

They might very rarely start breaking a door but once they would finish the server crashes:

Spawn a villager inside it
Set the difficulty to hard

```

Summon a zombie outside of it

/summon zombie ~ ~ ~ {CanBreakDoors:1b}

Make sure the gamerule mobGriefing is set to true
```
/gamerule mobGriefing true
