Integrate address book with distribution wallets

**Feature description**

Distribution address book wallet.

**Is your feature request related to a problem? Please describe.**
Address book API v1 binds addresses to multiple contacts.

**Describe the solution you'd like**
Reimplement address book in such a way that contacts are bound to distribution-only wallets instead of individual addresses .

**Describe alternatives you've considered**
A clear and concise description of any alternative solutions or features you've considered.

**Additional context**
Needs wallet API v2 , see #230 . Relationships should be established using URI namespace resulting from #232

API v1 behavior would be equivalent to using collection wallets .

**Possible implementation**

- [ ] Implement address backend as a relation from (contact , asset) `1` -> `many` wallet URI
- [ ] Group addresses by distribution wallet in GUI
- [ ] Adding address for collection wallets should display input control in GUI
- [ ] Adding address for xpub or similar automatic distribution-only wallet should reveal next item in deterministic sequence
