Replying to deleted tweets

[IBBoard]

In baedert/corebird#712, Baedert pointed out that replying to deleted tweets would fail. This could be caught with the streaming API for users we follow (because we'd see the deletion message) but the non-streaming API doesn't get informed about deletions.

I need to check what Cawbird does when replying to a deleted tweet. We shouldn't lose the text. Because that's annoying.

Currently we just pop up a "Forbidden" message, but it also returns the following data:

{"errors":[{"code":385,"message":"You attempted to reply to a Tweet that is deleted or not visible to you."}
