hsd Watch Only Wallet Simplification

Overview

The hsd wallet has an edge case regarding watch only wallet usage that results in the incorrect path being returned to the client. This will result in invalid signature creation because the wrong key will be derived and used to sign the transaction. Using an extra API call, it is possible to work around this problem right now, but it is not ideal and is fixable.
