tests: Ensure sorted/multi_a descriptors always generate different addrs

Sometimes the multi_a and sortedmulti_a descriptors will produce some of
the same addresses in the tests. This causes the wallets to start
generating addresses at a different index as they detect that one of
the addresses is used. This subsequently causes a test failure.

To avoid this problem, use descriptors that will produce unique
addresses by putting one of the multi_a in a different branch.
