Filling a cauldron with a water bucket and emptying the water cauldron produces splash sounds instead of water bucket sounds

Summary
When you're using a water bucket to fill the cauldron, or emptying the water cauldron using a bucket, it produces splash sounds instead of the normal water bucket filling or emptying sounds. This is inconsistent with how the water bucket sounds like.

Step to Reproduce
1. Get a cauldron and a water bucket.
2. Fill the cauldron with a water bucket, and then empty it.
3. Pay attention to the sounds.
---> It uses splash sounds.

Expected Results
It should use water bucket filling and emptying sounds on the cauldron to be consistent like when placing a water bucket on the ground and picking the water up again.
