I cannot create a one-to-one chat with a user that is already in a group chat.

Steps to reproduce

• Create chat with two other users
• Click on "Start a chat" to create a new chat
• Type the name of one of those users in the search field

@saveriob can you send logs for this one please? Where are you clicking 'Start a chat'?

I just sent the logs.
See the attached screenshot. A room with Andrea and Paolo already exists. I click on the + sign (first screenshot) to create a new chat with Paolo only. When I confirm (second screenshot), I land on the group chat again and no one-to-one chat is created.
