User avatar in chat search and no chat title duplicate

User avatar in chat search and no chat title duplicate

Show other user avatar for in chat searches and doesn't show chat title in them (chat title was repeating in all results and they are obvious same)

Description

When we search for messages in group chat, result list show group avatar and title in all results of other users. Which make it hard to identify who is user

In the code, DialogCell have useFromUserAsAvatar which if set to true will display user avatar not chat avatar. It's set to true in MessageSearchAdapter (in chat search) so it shows avatar.

And in DialogCell logic, nameString is set to user's name if useFromUserAsAvatar is true but chat is not forum to move user's name on title row of cell. And pretty large if condition is changed to avoid adding user's name from message row of cell.
