Watch-only address balance should not be included in the overall balance by default

Bug Report

Problem

The watch-only account balance is currently included in the overall balance display. Later, a setting will be added to change this, but for now, including watch-only balance in the overall balance display should be disabled by default, i.e. the balance on the main wallet screen should not include watch-only accounts balance.

Reproduction

1. Create a new profile
2. Add a W/O address

Expected result

The balance should be 0
