Tamed All Cat Variants Advancement Bug

Put the summary of the bug you're having here

What I expected to happen was...:
Nothing

What actually happened was...:
When I tamed a parrot in Minecraft survival (note: I am using 1.14 snapshot 18w47b), I got the Advancement that said I had tamed all cat variants. I am unsure if this is a bug, or a placeholder until the cats are introduced later on down the line.

Steps to Reproduce:
1. Play in snapshot 18w47b

2. Tame a parrot
