Return the ticket to developer as due to some other cases to be consistent we need to change the expected result:

1. Now there is no unnecessary error message -> ok

2. If to delete from the custom app from the current "New conversation", the first model from recent is set -> bug due to changed expected result We need to set the default icon and selected 'Not allowed model' [Volha Oct. 11th ] agreed with YH to leave as is: the initial expected result. If the conversation is focused, user deleted custom app => the next app from talk to is assigned.

3. Be sure to do the same for other New conversations, which are not focused. Expected: default icon and selected only "Not allowed model". Now it should be fixed and it looks in the following way:

4. Icons for the conversation with history appears after browser refresh -> bug Icon should be reset to default immediately.

5. For the conversation with history no need to select recent model -> bug
