[MC-170612] Villagers spawned by meeting points have frozen AI and do not move when that chunk is freshly generated

The bug

Despite ~~MC-153370~~ has been resolved as Cannot Reproduce, Villagers from meeting points REALLY have AI that becomes frozen when freshly generating new chunks. These don't go to bed, even if there are many free beds, don't work, don't breed and don't even move until a zombie or illager gets close to it, then it will try to flee. After that, its AI is frozen again.

How to reproduce

Start a new world
Use /locate to find a nearest village
Teleport there
Look at the meeting point
→ Observe that those villagers are not doing anything
