As a member of the fundaising team,
I want to know how much money comes in through each payment channel,
so that I can do fundraising more effectively
Acceptance Criteria:
- Report "Spenden pro Tag" shows "SUB" payment type data
- Report "Spendengruppen" shows "Sofortüberweisung" payment type data
Background:
Part of this story is to develop tests for this part of the application and to refactor this part to make it more testable. The end result doesn't need to be a Silex-based controller with a fully-fledged end-to-end test and unit test suite, but more of "Enough tests to prove that the new functionality doesn't break anything".
