[FIX] The unread section is not removed after receiving a new message and swipe to read

[reinaldonetof]

Proposed changes

Currently, when the user is sorting the chat list by Unread on top and there is an Unread Chat that contains a direct message or a message in a thread to read, then, if the user swipe to the right and press "read", the list isn't re-render.

Issue(s)

The "unread on top" setting is enabled. I receive a new message.
The unread section appears.
Swipe right and "read".
The new message icon was removed, but the unread section was NOT removed.
