What happened?

I connected to the internet after being offline for ~3 days, and Monal was syncing history from chats.
I left a channel while it was syncing history, and it disappeared from the Chats view for a moment, and then popped up again to finish syncing history until the most recent message.
As mentioned in the title, the chat is now considered a normal contact i.e. there's a call button, and in the Contact details view there's an Add Contact button instead of Join Channel or Leave Channel
I tried to leave another channel that was also still syncing history and the same thing happened. So it seems that this bug is reproducible.

Workaround: you can go to the Contact details, click Add Contact and the go to the Contacts view, swipe the entry and Remove Contact
