mark drafts in conversation with a red "draft" label

[sosnovsky]

Message in the red rectangle is draft, but it looks the same as other received or sent messages.
So for user it's not clear that this message is draft and wasn't sent yet.

agree, that needs to change

I could literally just say "draft" in red color next to the time. That would be enough for this issue for now.

@ekievsky please do this before continuing on the sharing extension. That one was a bigger issue than I thought.

can be tested with drafts made in browser extension - creating drafts in iOS will remain disabled
