Fix notification release issues (#925)

* fix: background polling issue for 1on1 messages, update the HomeDiffUtil.kt to include more cases to compare content equality, add synchronized ConversationNotificationDebouncer.kt and reduce the debouncer time

* fix: replace updateNotification to be thread-specific to fix unread behaviour and currently visible thread behaviour

* refactor: remove trimmed text limits
