Deltachat-android: Empty notification for voice and image messages

[adbenitez]

Received a voice message, but the notification is says nothing, it is just empty

• Platform (android/blackberry/anbox): Android 6.0
• Device: BLU
• Delta Chat Version: 0.200.0
• Expected behavior: Something like a text "Voice message", or "Audio" in the notification
• Screenshots:

I will have a look and will try to make the messages a bit more meaningful :).

It could just say:
📷 Picture – [optional message text]
🎤 Voice message

Right, I plan to reuse the messages we already use in the chat list (as preview) if an image / video / audio message is received, as those messages already contain an icon + some informational text.
