Dialog about "Disappearing messages changed" for image only messages
The "Disappearing messages changed" appears although it shouldn't.
Steps to reproduce:
- open a fresh, empty conversation
- enable disappearing messages
- (optional: send a text message and notice that the dialog does not appear)
- send an image message (without text) and see the dialog appear
It doesn't work just once, it works repeatedly and also after sending more text-only or image-with-text messages
