Restore the functionality to edit or reply to the last message in the `chatbar`.
This is achieved be moving the functions `getLastLocalUserMessageEventId` and `getLatestMessageFromRow` to `NeoChatRoom` as `editLastMessage` and `replyLastMessage` as `chatbar` no longer has access to `messageEventModel`.
The functions are also simplified as they only need to find the `eventId` and always from row 0 as this was the only use of the functions.

Make sure that the `updateNotificationState` function is called when the base state is loaded so that new rooms after startup have a valid notification state.
Fixesnetwork/neochat#583
We can't (easily) make this declarative, since there are no spaces on startup, causing the loader to be disabled,
making the repeater not load anything, which means the loader stays disabled.
We should figure out a better solution, since this means that the drawer doesn't open immediately when joining a space,
but for now this fix is better then the current bug.
Create a reaction model that provides all the required data for `ReactionDelegate` so that none need to be calculated in QML.
This also cleans up the API for `ReactionDelegate`
Instead of issuing a new notification for every message, bundle them by
room.
It looks like the code was originally designed to do that and somehow we
forgot along the way.
It also fixes the leaking in m_notifications as we were never cleaning
after it.
What happens is roughly: The notification is received in one account and marked as received locally.
In the other account, the event is marked as "read" in the json, which makes us delete it from the
received messages. Then it is received on the first account...
Limit the maximum number of avatars shown for other user read markers and collapsed state events

Unread count is deprecated and notification count should be used in all cases. As such remove unreadCount and use notification count in all places it was being used.
