[Syncing] Blocked contact

[igor-sirotin]

Bug Report

This issue is originating from #10288.

There're various problems with syncing blocked contacts.
Problem is reproducible with both Mobile->Desktop and Desktop->Desktop.

1. Random timeline chats arising (desktop)

1. Alice, David: create new profiles
2. Alice: add David as mutual contact
3. Alice: pair a new device
4. Alice: block David
5. Alice [device-2]: note that:
   • David is blocked
   • A chat with ourselves appeared
   • A timeline channel appeared

Logs: 1.log

2. blocked property is not synced during local pairing

1. Alice, David: create new profiles
2. Alice: add David as mutual contact
3. Alice: block David
4. Alice: pair a new device
5. Alice [device-2]: note that David is not in blocked list (though it's not in contacts list as well)

Alice [device-1]	Alice [device-2]

Though if Alice blocks David while both device-1 and device-2 are running, the blocked property syncs with not problem.

This one is reproducible purely with status-go. There's indeed several bugs, including unwanted timeline chats.
I'm working on a test that covers this and the fixes as well.

The fix is here: status-im/status-go#3799
Already in status-desktop master branch. Tested both cases.
