[FIX] Thread message flickering while thread parent isn't found

[djorkaeffalexandre]

Proposed changes

We don't need to check the previous message for a thread sequential.

Issue(s)

How to test or reproduce

• Create a new channel (not on the app)
• Send a first message
• Send a second message replying the first one (to create a thread) containing some other message on the content (to add a Reply component)
• Open the channel on the app (you might have to clear cache before doing this)
