[lib] Re-broadcast account deletion on own devices

Summary:
Address ENG-8606.
When own device receives account deletion message, it re-broadcasts it again. However, it skips own devices to avoid vicious circle.

Depends on D12944

Test Plan:
Deleted account when having device list with a secondary device and a peer in auxUserStore.

• Verified that both peer and my device received the ACCOUNT_DELETION message.
• Additionally, the peer device received it twice.
• Both primary and secondary device were logged out
