fix(messenger): make sure chats have an unread count of 0 for channel…

…s you can't view

Fixes status-im/status-desktop#14421

The problem is that you can receive messages to  a channel, then later, before marking them as read, a permisison is added to them, so you no longer have access.
Then, you can't even mark it as read if it's hidden.
Here, I fix it by setting the unread count on Init at 0 if the user doesn't have view access to it.
