Incorrect model is set in new conversation if in previous chat model was applied but no message was sent

[VolhaBazhkova]

EPAM AI DIAL chat version

0.14.0

What happened?

1. Create new conversation based on model1 -> send a message
2. Create new conversation -> note that model1 is set automatically -> ok
3. In chat setting in the header change model1 to model2 -> click on Apply changes -> current chat icon is changed to model2 -> ok
4. Create new conversation -> note that the model1 is set -> bug

Expected result: model2 should be set

Note: model2 is set in new conversation only in the case when model is responded. Note: in 13 version model2 is used if it was applied in previous chat, model response is not required action
