Bug: multi-xpubs for contacts are not differentiated

[coolaj86]

I had a contact. He misplaced his wallet and so I added him again with a different xpub. The problem is that old addresses referenced by HDPath only, not by the index of the multiple XPubs, so now I get this:

Error: check fail: hdpath 'm/44'/5'/0'/1/1' for 'Xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' derived 'Xyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy'

Immediate Workaround

Open the ~/.config/dash/pay-wallets.json and give the new version of him a different name.

Codefix Workaround

Continue to iterate over the contact's wallets on error and only fail if no wallet matches

Future Solution

Use ULIDs to identify contacts and associate each hdpath with a ULID and Account Index. The ULID can represent either a wallet phrase + account index, or an xprv, or xpub.
