fix(communities): properly delete remove chats when handling community updates
fix(communities): properly delete remove chats when handling community
updates

When channels where removed from communities by the community owner,
community members would not remove the chats in their own databases.

See https://github.com/status-im/status-desktop/issues/8000 for more
info.

This commit ensures that nodes delete removed chats from their local
chats table and also deregister the corresponding transport filters.
