Villager work stations not working right

Put the summary of the bug you're having here

What I expected to happen was...:
I tought that when you have 2 villagers and 2 work stations they would use different stations and would have different trades.

What actually happened was...:
I had 2 villagers and I had 1 work station placed down. I brought the second villager to the area where i had the station. The villager that did't have a job picked the same work station as the first villager had. So there were 2 villagers on the same station and they had the same trades. And the second villager didn't change the station when I placed down his own station. This happens automatically when you bring a villager to area that has already a station placed and it has happened with also 3 villagers on the same station with same trades, even tough they could have had their own ones.

Steps to Reproduce:
1. Put down a work station.
2. Bring a villager to the station.
3. Bring another villager to the same area with the station.

4. The villager without a job picks the same work station as the other villager has picked and gets the same trades as the other one.
