Address book - Separate for each wallet

[Myke500]

Address book can be accessed by all wallets on a single xCore application. (All users the have access to the computer)

Separate address books per wallet would be a better solution in a shared application or shared computer setting.

Make the address book index only available to the wallet the added the address. Other wallets will not be able to see the same addresses added by other wallets(users)

The screenshots show that when using the same computer, running the same application of xCore (containing multiple wallets):
test wallet 2 has 2 addresses added,
however when we look at the address book in test wallet 3 we see that the addresses added from wallet 2 also show up in wallet 3.

Screenshots:
Test wallet 2 Address Book - with 2 addresses added

Test Wallet 3 Address Book - No addresses added

Additional Context:
This is a low priority issue at this time, it will become more relevant as the user base grows.
