Generate predictable UA structure for the first 3 test vectors. 

This makes the first few test vectors easier to use by wallet
implementers. The generated UAs now have the following structure:

* Account 0: P2PKH + Sapling
* Account 1: P2PKH + Sapling + Orchard
* Account 2: Sapling + Orchard

The remainder are randomly generated as before.
