Fix number issue

** This is a failing test **

So I noticed that this test was incomplete because it might preclude
the use of real code leading up to the `#` character, so I just lazily
put `1 + 1` there and realize that there's an issue with how the
converter is working. I'm not sure at all what the cause is, because
it's looking up 1️⃣ => "one" => 1 correctly independently.
