This two-line function wasn't really carrying its weight, and it just made it harder to refactor the overall codepath. Eliminating the function forces us to mock at a slightly deeper level, which is probably a good thing for what the test intends to do. The deeper mock still verifies that we're sending the message (good) without digging into all the details of how we send it (good). Note that we will still keep around the similarly named `fail_with_message` helper, which is a lot more useful. (The succeed/fail scenarios aren't really symmetric here. For success, there are fewer codepaths that do more complex things, whereas we have lots and lots of failure codepaths that all do the same simple thing of replying with a canned message.)
