Fix order of callbacks

Delivery comes before inbound. The order of the URLs was jumbled in two
places:
- in the view function
- in the Jinja template

So as the user saw it the URLs were in the right order, because the
double jumbling cancelled itself out. But it made the code _really_
confusing to read.
