This pull request removed the override of `process_payments!` which was based on v1. Spree v2 has an additional check: An order in payment state requires a payment. Some specs didn't care and didn't create payments before transitioning to `complete`.
We need to purposefully enable deliveries for the deliveries array to
list this email. Otherwise the delivery logic is not executed and thus
the deliveries array never filled.
The way we set up email sending completely changes with Spree 2. This
change encapsulates that code in a single method so that it can be
changed easily and doesn't create further merge conflicts while we are
still working on the master branch and the Spree upgrade.
