The advancement "Two by Two" can be achieved by just breeding turtles

The bug

When breeding a pair of turtles, regardless of what animals you bred before, you will immediately get the "Two by Two" advancement.

What I expected to happen was:

After feeding and breeding the turtles, I should've only gotten the advancement "The Parrots and the Bats".

What actually happened was:

Instead of only getting the advancement "The Parrots and the Bats", I got the advancement "Two by Two" (breed every animal in the game) too.

Note: It doesn't matter if you've bred an animal before or not, it will always give the advancement "Two by Two". The gamemode you're in doesn't matter too.

Steps to Reproduce:

1. Find/spawn turtles
2. Breed them with seaweed
3. Notice that you'll get the "Two by Two" advancement
