There's no villages in superflat

There's no villages in superflat

What I expected to happen was...:
The commands /locate Village or /locate New_Village should return a village.
I should be able to find a village by flying around.

What actually happened was...:
/locate doesn't return any village and I can't find villages by flying around.

Steps to Reproduce:
1. Open 18w48b
2. Create new superflat word with Overworld preset
3. Try to find a village
